Tsukushi Makino's family falls on hard times when her father loses his job. She finds herself in a bad situation while searching for a lucrative job. Kinsan rescues her and later helps her find a job. Meanwhile, Tsukasa Domyoji makes up his mind to forget Tsukushi by moving to New York.
"Tsukushi Makino is from a poor family, but she's attending an elite school for the super rich. Her life has become intertwined with the ruling boys of the school in a whirlwind of love and confusion. Tsukasa is headed for New York to break away from his Tokyo life, but just before leaving Rui whispers something to him. When this news finally sinks in Tsukasa goes into another one of his frenzies. Financial troubles weigh heavy on the Makino family as Tsukushi's father is out of a job. It becomes clear that they are completely dependent on her marrying a rich boy from Eitoku Academy. A new boy enters the scene! He is a bit of a nut, but is determined to help Tsukushi."
The morning after the basketball match, Tsukasa Domyoji recounts a childhood story to Sojiro Nishikado. In it Tsukasa describes wanting a teddy bear owned by Rui Hanazawa. When Rui refused to give it to him, Tsukasa grabbed the bear and accidentally tore it apart. Tsukasa resolves to stop fighting with Rui over Tsukushi Makino, saying "We can't tear her apart the same way." Meanwhile, Tsukushi returns home to learn that her father has lost his job and the family has to move. Once they settle in their new home, the family puts all of their hopes in Tsukushi marrying rich. Not wanting to tell them that Tsukasa and Rui are no longer interested, Tsukushi sets out to find a new part-time job.
In hopes of earning quick money, Tsukushi agrees to have photos of her uniform taken. The situation turns sketchy and the men restrain her, just when a delivery guy arrives. He helps her escape by beating up the three men. At school, Rui reveals to Sojiro and Akira Mimasaka that nothing happened with Tsukushi since he could not betray Tsukasa. Meanwhile, Tsukasa informs his sister about his plans to move to New York as soon as possible. After telling the delivery guy her plight, he helps Tsukushi find a good job at a fast food restaurant. The following morning at school, Kazuya Aoike runs up to Tsukushi. He informs her about Tsukasa moving to New York. Tsukushi immediately starts running to go see Tsukasa.
Tsukushi feels hurt about Tsukasa not telling her about him leaving. He treats her coldly, saying "Why do I have to let you know?" Tsukushi slaps him and bursts into tears, before she says him leaving will be a "relief." At work, the delivery guy, whom she nicknames "Kinsan," is helping her. Tsukasa comes to say goodbye, but gets into a fight with Kinsan. He leaves, promising to never come back. The next day, Sakurako Sanjo walks up to Tsukushi and tells her that she "can make [Tsukasa] stay." At the airport, Rui whispers in Tsukasa's ear that he thinks Tsukushi actually loves him. The words do not sink in until he gets on the plane. Tsubaki prevents him from leaving. Meanwhile, Tsukushi watches a plane fly by.
Later, Tsukushi has improved at her job but Kinsan notices that she looks down. He decides to cheer her up by inviting her out. The next day, her mother mistakenly thinks Tsukushi is getting ready for a date and forces her to dress up. At the same time, Tsukasa is left on his own in New York when he finds a magazine with Kinsan's face on it. While out with Kinsan, Tsukushi starts to think that his family is poor like hers. He tries multiple times to correct the misunderstanding, but Tsukushi interrupts every time. After saying goodbye, Tsukushi is walking home when she hears footsteps. She kicks the perpetrator, discovering Tsukasa. Kinsan then walks up and Tsukasa throws the magazine at him, exposing his true identity.
