"Hi. It's been a while. To those of you who've bought this comic...To those who've borrowed it from a friend...To those who are reading it in a bookstore...I'm happy to see you again! Thank you for all your letters. I've received countless cassette tapes to listen to while I work. I'm so happy and I do listen to them all. I'm really, really grateful to those of you who have sent me these tapes."
Tsukasa Domyoji is left brokenhearted when he discovers Tsukushi Makino in the arms of Rui Hanazawa. First, he kicks Rui out of the F4, calling him a traitor. Tsukasa later vows to have Rui and Tsukushi expelled from school. In the meantime, his older sister comes back from Los Angeles.
"Upon Rui Hanazawa's return from France, Tsukushi's feelings for him also return. Together, they share a tender moment that is witnessed by Tsukasa. Tsukasa is consumed with rage and swears vengeance upon both of them in spite of the well-meaning interference by his recently arrived infamous older sister!"
Rui Hanazawa and Tsukushi Makino have just kissed when the two look up and see Tsukasa Domyoji. He punches Rui and then turns around to leave. Tsukushi stops him, trying to explain. He interrupts her saying "You took my heart and sliced it into ribbons." Tsukushi collapses in tears. The next morning, they discover that Tsukasa has left on his jet. Everyone is forced to take Kazuya Aoike's boat home. Two days later, Tsukushi goes to school and readies herself to apologize to Tsukasa. Before she can do so, she overhears the F4 fighting, ending in Tsukasa declaring "You're not one of us" to Rui. Tsukushi then attempts to apologize to Tsukasa, but he ignores her. Later, Rui asks her on a date to cheer her up.
Despite her resolution to "forget everything," Tsukushi finds herself thinking of Tsukasa during her date with Rui. Things turn awkward when Tsukushi mentions Shizuka Todo. It gets worse when Rui accidentally walks in on her in the restaurant bathroom. Afterwards, he finds her embarrassment amusing and invites her to go somewhere they "can be alone." At Rui's house, Tsukushi is nervous about what he may be expecting but he only ends up falling asleep. On her way home, she overhears Akira Mimasaka and Sojiro Nishikado talking about Tsukasa and Sakurako Sanjo. She finds them talking and laughing nearby. Sakurako sees her watching and smirks, before following Tsukasa to his house.
For several moments, Tsukushi stands thinking about what just happened. A guy, meanwhile, is trying to get her attention. She yells at him, before a woman steps in and forces him to leave. The women takes her to her house and introduces herself as Tsubaki Domyoji. Tsukushi hides before Tsukasa and Sakurako can see her. However, she becomes lost in the huge mansion. Tsukasa later finds Tsukushi and becomes livid, but Tsubaki saves her. Over dinner, Tsukushi becomes drunk and reveals a bit about what happened between her and Tsukasa. Tsubaki has Tsukasa carry her to a room. Later, Tsubaki asks her not to "give up on Tsukasa" yet. Walking home that night, Tsukushi thinks "I have no right to be with him anymore."
The next morning, Tsubaki asks her brother about school and the F4. He becomes angry when she says Rui's name and declares "The days of Rui in the F4 are gone forever." At school, Rui leaving the F4 over Tsukushi is the only thing the students are talking about. Some girls approach Tsukushi, angry that she "tricked" Rui. He turns up at that second and defends her, saying "That's none of your business." A short while later, Tsukasa, Sojiro, and Akira go to meet a limo. In it is Kazuya Aoike, whom Tsukasa announces is now a member of the F4. Happy at his good fortune, Kazuya goes up to Tsukushi. Tsukasa tells him he can no longer speak to either Tsukushi or Rui. He then announces his plan to have the two expelled.
