She was born into an average, middle-class family. Her father worked at AC Electronics, while her mother was a housewife. Yuki was the second of two daughters, her sister being a few years older.
Yuki attended N Middle School, where she met her best friend Tsukushi Makino. In their third year, Tsukushi forced a boy to apologize to Yuki when he made her cry. Yuki and their friends cried when they learned that Tsukushi would be attending a different high school from them. They were worried about how she would fare at Eitoku Academy, but hoped she would make friends.
Tsukushi: "Well, I'm not getting involved with anything at this school. I've got nothing in common with these people anyway."
Yuki: "Is this you talking? Tsukushi, you were always ready to jump in and help when there was trouble. Like that time in ninth grade, when I was teased by a boy and cried. You fought for me. You even made him apologize. It's like the kids at Eitoku have never seen your good side."
When Tsukushi began attending Eitoku, Yuki was always ready to listen to her problems. She was especially interested in hearing about the F4 since she thought the guys at her own school were "lame." Yuki noticed that Tsukushi had changed from a person that was "always ready to jump in and help" to someone who did not want to get involved. She felt disappointed that Tsukushi's classmates "[had] never seen [her] good side." Several days later at work, Tsukushi talked to Yuki about her classmates inviting her to a party. Yuki was impressed that high school students were going to a party in Roppongi. Sojiro Nishikado and Rui Hanazawa then walked into the store. Yuki was very excited about meeting them. She guessed that Tsukushi liked Rui based on the way she was looking at him.
Several days later, Tsukushi visited Yuki to tell her about an incident with Tsukasa Domyoji. She then asked Yuki to attend Shizuka Todo's birthday party with her. They were at a lost about what to wear until Yuki's sister offered her help. Her style was not exactly to their taste, though they went along with it. Tsukushi's friend Kazuya Aoike picked them up and escorted them to the party. There Sojiro flirted with Yuki, which made her feel dizzy. Tsukushi dragged her away, warning her "If you get taken in by him, you'll end up pregnant." Seeing a number of celebrities, the girls felt that they "[stuck] out like sore thumbs." After Shizuka renounced her family name, Yuki and Kazuya ran up to Tsukushi to discuss it. Yuki called Shizuka cutting her hair a "waste," but still thought she was "wonderful."
Tsukushi visited to Yuki's house several days later. Yuki noticed she was "gloomy" and asked her what happened, just as her sister entered the room. She then invited Tsukushi to go clubbing to cheer her up. Yuki excitedly agreed. At the club, Yuki's sister challenged another girl for the best spot on the platform. When the girl knocked her off, Yuki rushed to her side. Several weeks later, Tsukushi was talking to Yuki about Tsukasa and Seinosuke Amakusa. Yuki said "Tsukasa really loves you, doesn't he?" but Tsukushi denied it. She then asked Tsukushi about her feelings towards Seinosuke. Tsukushi replied "I think it was better when I thought we were both poor." Yuki encouraged her to "live true to [her]self." Tsukushi then asked her to attend Seinosuke's party with her, but Yuki had to decline.
Tsukushi: "Don't take it personally. They're just being themselves"
Yuki: "How could she say, 'Too bad you didn't die'?! That was awful! I mean... How can you not take that personally?!"
The day after Christmas, Yuki was working with Tsukushi when Sojiro, Rui, and Akira Mimasaka walked in. Sojiro offered to help them sell product. The girls were confused about what followed. The store was sold out within a few minutes. Their boss gave them their five percent commission, which totaled 500,000 yen. The guys invited them on a trip to Canada. Tsukushi was unsure about accepting, despite Yuki's enthusiasm. After work, Tsukushi told her about borrowing a million yen from Tsukasa and that she felt she still owed him. She later decided to go after all. When they boarded the plane, they were joined by some of Tsukushi's classmates who Yuki thought were "classy and mature." At Tsukasa's villa, Yuki met him for the first time. She described him as "intense" and "good-looking."
The following night, Yuki had a bath after being out on the slopes. Rui, whom apparently had not noticed her earlier, asked "Did you come here with Tsukushi?" It came to light that Tsukushi's classmate, Yuriko Asai, had tricked her into going out during a blizzard by claiming that Yuki was outside. Tsukasa left shortly to find her. Sojiro and Akira Mimasaka comforted a crying Yuki, assuring her "Tsukushi and Tsukasa are both fighters." The next morning, they returned to the house. Tsukushi was fine except for a sprained ankle. Yuki pointed out that she and Tsukasa were both blushing, which caused them to blush harder. After he left, Yuriko and her friends revealed that they were not remorseful. Tsukushi told Yuki not to take their words "personally." Yuki, however, felt emotional about it and started to cry again.
A few days after the trip, Yuki and Tsukushi visited the shrine together. She wore a kimono borrowed from her sister. They met an old woman who gave Tsukushi a foreboding fortune. Yuki called her a "fake," but Tsukushi seemed to believe her. Switching the subject, she told Tsukushi about their middle school reunion. They attended it the following day. It was cut short when Tsukasa, who happened to be there, attacked their old classmate Shingo Oribe. Tsukushi began arguing with Tsukasa, who reminded about saving her with mouth-to-mouth resuscitation. She started to rub her lips hard and Yuki had to stop her. Tsukushi eventually ran out of the restaurant and Yuki followed her. She then told her "How can I face everybody after this?" Yuki assured her that their friends would understand.
"I don't think you'd fit into their world, Tsukushi. And after everything you've suffered at Eitoku, I want you to be happy. You'll probably have nothing but heartache if you keep seeing Tsukasa."
Some days later at work, Tsukushi told Yuki about Tsukasa's birthday party and him wanting to introduce her to his mother. She told her "Just like you're his fiancée." Tsukushi was concerned about his present. Yuki suggested something homemade. The day after the party, Tsukushi told Yuki about Kaede attempting to bribe her. She asked her if she intended on still seeing Tsukasa. Tsukushi admitted "I can't enter their world." Yuki sympathized with her, saying "You'll probably have nothing but heartache if you keep seeing Tsukasa." Tsukasa's mother's secretary then entered the store. Yuki waited for her to come back. They then went out to a fast food restaurant. Tsukushi complained about Tsukasa running off with his newly revealed fiancée. Yuki said it "must have been a mistake," but Tsukushi remained angry.
Several days later, Yuki and Tsukushi were exhausted from their shift. They said goodbye and Tsukushi wished Yuki good luck on her test. Sometime later, Tsukushi revealed that she was going to be living her on own since her family was moving away. Yuki told her "I might not be of much help, but you can lean on me when you feel overwhelmed." She later came over to Tsukushi's place to paint and re-paper the doors. After they were done, Yuki about Tsukasa and his fiancée breaking up. Tsukushi dodged her questions. A couple days later, Tsukushi told Yuki about standing up to Tsukasa's mother and deciding to fight her. Yuki told her "There's no justice in this fight. It's reckless." Tsukushi was determined. Yuki then voiced worries about Tsukushi being able to afford her daily expenses.
"He's a boy in one of my classes who I exchanged pager numbers with a ways back. I didn't think anything of him at first. He was just one of the guys. Remember, I never cared for the long-haired street kid kind of guys? He seemed like the playboy type so I was leery about having him for a boyfriend, but as I talked to him, I found he was pretty down-to-earth."
Yuki later began dating a classmate, Nakatsuka. She was not initially interested in him, thinking he seemed like a "playboy." Her opinion of him changed on their first date, during which she had her first kiss. Sometime later, Yuki received a call from Tsukushi. She told her all about Nakatsuka, before Tsukushi had a chance to tell her her news. The next day, Tsukushi visited Yuki and told her about being a live-in maid at Tsukasa's house and that she was dating him on a trial. Yuki was very surprised. Tsukushi asked for her advice on things to do with Tsukasa, but then felt he would not do any of Yuki's suggestions. Yuki told her that the relationship "would [not] last" if Tsukasa could not compromise. She then suggested that Tsukushi and Tsukasa go on a "poor man's date" with her and her boyfriend.
That weekend, Yuki and Nakatsuka met up with Tsukushi, who told them that Tsukasa was not coming. However, he arrived seconds later. They first went to eat. Nakatsuka made some comments to Tsukasa, leading Yuki to tell him "Don't be so rude." The two girls became uncomfortable due to the tension between their boyfriends. Next, they went to an amusement park when Nakatsuka presented some tickets. There they split up and met up later. Yuki told Tsukushi that she felt Nakatsuka was not "trying to be mean" to Tsukasa. A few minutes later, the girls discovered Tsukasa punching Nakatsuka. After Tsukasa stormed off, Nakatsuka told Tsukushi "You probably let him get away with a lot." He then left as well. The next day, Yuki confessed to Tsukushi that "maybe [she] was putting up with a lot from him."
Yuki: "I am mad. I'm mad at myself for being so happy about going out with a guy like him."
Sojiro: "Right? So let's go, then. Otherwise you'll spend the rest of your life feeling the same way. Let's get things off your chest. And after that, you should have a great love affair and forget everything."
— Sojiro offers to help Yuki after Nakatsuka cheats on her[src]
Yuki and Tsukushi happened to overhear Nakatsuka tell another girl that he and Yuki were "over." He said other rude things about Yuki. When he finally noticed Yuki, he acted as if he did not know her. She then ran off and burst into tears by the side of the road, where she was found by Sojiro. He brought her to his house. Yuki told him everything. He prepared her some tea and compared its bitterness to love, saying "A difficult and bitter love relationship helps a person to mature." Yuki felt better afterwards. Then Sojiro decided that he would help her get back at Nakatsuka. She was hesitant at first. They went to a night club, where Yuki watched Sojiro embarrass Nakatsuka by convincing his girl to dump him. Sojiro then grabbed Yuki and asked her "Do you know this guy?," to which she answered that she did not.
Tsukushi and Tsukasa arrived in the midst of the confrontation. They all left after Tsukasa knocked out Nakatsuka. Yuki admitted to Sojiro "I feel completely over him." They went to a restaurant, where Yuki apologized to Tsukushi and Tsukasa for everything. Sojiro walked her home after. That weekend, Yuki went on a date with Sojiro, whom wanted to show Tsukushi and Tsukasa a real date. As predicted, the two followed them. Sojiro and Yuki talked about the other two. He told her that Tsukasa "[took] good care" of Tsukushi. Yuki then asked "Don't you take good care of the girl you like?" Sojiro replied "I may be good-looking, but I'm not a good guy." They then went to a hotel, where they waited with Rui and Akira. Tsukushi and Tsukasa eventually showed up to their room. Yuki apologized to her.
"You're not yourself, Tsukushi! You think I haven't noticed?! Your smiles don't reach your eyes anymore. I'd made up my mind to wait until you were ready to talk to me. But inside, a part of me was worried about what would happen to my family if you loved Tsukasa. To think, I can't even be there for my best friend when she has problems of the heart."
Still at the hotel, Tsukasa revealed that he and Tsukushi saw his mother in the hallway. Yuki was surprised by the way the F4 spoke of her and asked "Is she really such a scary person?" She became worried for Tsukushi and suggested for her to stay at her house. The next day at school, Yuki was asked to come home by her mother. She left immediately and ran into Tsukushi on the way. Her distraught mother told her that they had to start packing due to her father's sudden transfer. Tsukushi left after saying "Please hold off on packing up." Soon after Tsukushi disappeared, Yuki's father's transfer was canceled. Yuki was unable to get ahold of her. She later talked to Kazuya about Tsukushi, but he had not heard from her either. Yuki was upset that Tsukushi took on the problem by herself "without consulting anyone else."
Some days later, Tsukushi returned to Tokyo and Yuki went to see her with several others. She and Kazuya immediately started crying and apologized to her. That night, Yuki spent the night with Tsukushi, Sakurako Sanjo, and Shigeru Okawahara. After the other girls had fallen asleep, Yuki told Tsukushi that she had good friends. Yuki, Sakurako, and Shigeru left around dawn to prepare for school. They all met later at a café. Sakurako and Shigeru surprised the other two by setting up a group date. Yuki was nervous, but went along with it. One of the guys, named Kiyonaga, shocked the girls because of his resemblance to Tsukasa. They tried to carry on normally, but Tsukushi was unable to. The girls left after the guy poured his drink on Tsukushi. Outside, Yuki and the others lost track of her.
A few days later, Yuki was surprised when Tsukushi revealed she was dating Amon Kunisawa, who had posed as Tsukasa's cousin Kiyonaga. She insisted that their relationship was "platonic," but Yuki was dubious. She then asked "You've given up on Tsukasa?," to which Tsukushi claimed that there was "never anything between [them]." Two days later, Yuki and Tsukushi were discussing their sleepover plans when Amon walked in. She was taken aback by Tsukushi's conversation with him. Once he left, she asked "What did you mean by 'Don't touch me'?" Tsukushi avoided answering, leading Yuki to snap. She broke down and cried, saying "To think I can't even be there for my best friend when she has problems of the heart." Tsukushi spent the night at Yuki's house. In the morning, they left in opposite directions.
Crush on Sojiro
"You told me this as well, didn't you? 'Any guy who takes good care of the girl he loves is a good guy.' That made me think that there probably once was a girl you wanted to take care of. Why, then, do you run and hide yourself amongst all those other girls?"
A couple days later, Yuki was visited by Sojiro at the store. He bought everything so that Yuki would be let off work early. At a café, he asked her if it would be a "problem" should things "go well" between Tsukushi and Tsukasa. Yuki told him that she wanted Tsukushi to "find happiness" and that her family would weather any problems that came their way. Sojiro commented that Yuki had become "strong." She credited her new strength to Sojiro. His date then came to meet him and he left. Now by herself, Yuki whispered "I feel like an idiot." The next day at work, she confessed to Tsukushi that she had fallen in love with Sojiro. Tsukushi reminded her that he was a "playboy." Yuki felt that it was too late to stop herself, despite feeling that she would be hurt in the end.
That afternoon, Yuki was invited by Sakurako to Akira's house for a party. There Sojiro helped her put on a kimono. Later on, Yuki confessed to Sojiro "I like you." He only thanked her, so she insisted that she was "serious." She was then offended when he offered to date, kiss, and sleep with her but nothing more. Yuki slapped him but immediately apologized. Recalling something he said, Yuki questioned why he amidst flings if there was a girl he wanted to take care of. Angry, Sojiro soon walked off. Tsukushi, whom had overhead, attempted to comfort Yuki. However, she was not crying and only asked for encouragement. Before leaving, Yuki witnessed Tsukushi confessing her feelings for Tsukasa. At work, she revealed how happy she was for Tsukushi and reminded her to never run away like she did before.
After work, Yuki waited for Sojiro outside his house. She found that he had already reverted to his old self. Sojiro told her that he never got involved with girls who were "too close" and therefore "trouble." Yuki was shocked, but recovered to ask "Can I have the full course?" She then gave him her number, before running off. The next day after work, Yuki was chatting with Tsukushi about Tsukasa when she received a call from Sojiro. She suddenly asked Tsukushi to borrow her skirt. Sojiro took Yuki out for dinner and presented her with a room key afterwards. In the room, Yuki trembled as Sojiro hugged her. He stopped, telling her to "stop forcing [her]self." Yuki wanted to be with him if this was the way. Sojiro then admitted that he was trying to "scare" her, before telling her about his "one and only love."
She was generally considered cute though not particularly beautiful, much like her friend Tsukushi. Yuki had short, curly hair which she usually wore down. She had soft, brown eyes. Her wardrobe usually consisted of casual wear, especially since she did not wear a uniform to school.
Personality and traits
Yuki was generally a normal girl from an average family. She was considered naive for her age, especially with men. Her best friend Tsukushi was particularly protective of Yuki because of her naivete. She even followed Yuki on her date with Sojiro, though it actually was not a date. Yuki hated conflict of any kind, saying it gave her a stomachache. However, after several trials, she was able to handle conflict on her own. She first began gaining strength and maturity through Sojiro, whom she developed feelings for. Yuki and Sojiro had a special bond, which ultimately helped her become a confident person.
Kind and loyal, Yuki was thought of as a good friend. She often gave Tsukushi advice, which Yuki always thought out logically. After Tsukasa's mother hurt Yuki's family, she was scared of Tsukushi and Tsukasa getting back together. She ultimately wanted her friend to be happy and supported her.
She is played by Ai Sasamine in Hana Yori Dango (1995). Yuki and Tsukushi attended the same high school. She is a bit disappointed in her "third-rate" college, but content with her life. Despite going to different schools, the two still regularly see each other at their part-time job. Tsukushi often confides her troubles to Yuki. As such, she is very perceptive of Tsukushi's feelings. Yuki realizes that Tsukushi loves Tsukasa and encourages her to go after him.
Rainie Yang portrays a version of Yuki, renamed Xiao You, in Meteor Garden (2001). Yang was originally cast to play Li Zhen, before the producers switched her to Xiao You. Like her manga counterpart, Xiao You is Shan Cai's (Tsukushi) confidante, dates Zhong Ze (Nakatsuka), and develops feelings for Xi Men (Sojiro). Towards the end of Meteor Garden, Xiao You moves to Canada, but makes a brief return in an episode of Meteor Rain (2001).
Kotono Asanoha plays her in the 2019 Takarazuka musical, Hana Yori Dango. Her role in the musical is small as she only appears in about five scenes. Yuki develops a crush on Sojiro, which he seems to reciprocate. At the end, she goes on a date with Sojiro.
