The fall term at Eitoku Academy that Tsukushi has been dreading starts. In contrast, Tsukasa gets there early in order to perform a childish prank on her. He later finds Rui with Tsukushi at the emergency exit. Yuriko and her friends show him a video of the two, which sends Tsukasa into a rage.

Tsukushi attends Shizuka's birthday party with Kazuya and Yuki Matsuoka. There Shizuka makes the announcement that she will be giving up her family name in order to become a lawyer in France. Meanwhile, Tsukushi feels awkward about seeing Tsukasa for the first time since the incident.

Concerned for Rui, Tsukushi begs Shizuka to stay in Japan. Shizuka clearly explains her reasons for leaving. Rui overhears the conversation and becomes angry. After Shizuka leaves, Tsukushi yells at Rui to follow her. He reveals that he was already planning to.

A photo of Tsukushi and Tsukasa causes everyone at school to believe they are dating. Yuriko and her friends attempt to befriend Tsukushi. They take her to a club, where she meets Thomas. Tsukushi wakes up the next morning in a hotel room with no recollection of what happened.

When Rui comes back from France, Tsukasa tells him that he and Tsukushi are dating. Rui later flippantly asks her if she will go out with him. Meanwhile, Sakurako is being bullied after the others discover an old photo of her. Tsukushi ignores it at first, but steps in eventually.

Tsukasa declares that he will have Tsukushi and Rui expelled from school. He blackmails the principal by threatening to pull his family's funding. His sister storms into the office. She suggests they settle the matter through sports. Rui proposes a three-on-three basketball match.

Before the match, Tsukasa promises to call it off if Tsukushi says she loves him. She remains silent, rejecting him. Rui's team is losing badly when he comes up with a new tactic to gain points. He distracts Tsukasa by acting affectionate towards Tsukushi, causing him to make mistakes.

Tsukasa makes up his mind to go to New York. At the airport, Rui gives Tsukasa a voice recorder that says "Nothing happened between Makino and me." After learning that her father has lost one million yen, Tsukushi receives a call from Tsukasa asking her to come to Canada.

After Tsukasa promises to loan her the money, Tsukushi makes her way to Canada with the rest of the F4 and Yuki. Yuriko and her friends tag along as well. Later, a jealous Yuriko lies to Tsukushi by saying she saw Yuki go outside. Tsukushi goes into the blizzard to find her but becomes lost.

Tsukasa runs outside to save Tsukushi. He carries her to a deserted cabin, where they spend the night in one another's arms. The next day, Tsukasa attempts to confess his feelings to her. Tsukushi, however, thinks he is talking about the loan and promises to pay him back.

After returning home, Tsukushi feels awkward around Tsukasa. She later meets Junpei Oribe, a freshman at Eitoku. He reminds her a bit of herself. Junpei offers his hand in friendship and reveals his secret by dragging her to a photo shoot. There he ropes her into posing for photos with him.

A photo of Tsukushi and Junpei makes the cover of a magazine. Tsukasa becomes angry, which leads to him beating up Junpei. He confesses his feelings to Tsukushi again, but she does not answer him. A couple days later, she becomes a bullying target again after receiving another red card.

Tsukushi is kidnapped by Junpei and his partners. He reveals to her that he has a grudge on Tsukasa and is using her to lure him there. Tsukasa arrives after receiving a note for him to "come alone." He allows himself to get beat up by the guys in order to protect Tsukushi.

Tsukushi wakes up in the hospital. The F4 play a trick on her by pretending Tsukasa has died. Tsukushi breaks down crying and admits to Tsukasa about how scared she was of him really dying. Junpei comes to apologize to her for deceiving her, but Tsukushi is not ready to forgive him.

Tsukasa invites Tsukushi to his birthday party. Before entering the party, Sojiro reveals that Tsukasa's mother, Kaede, will judge her as a potential fiancée. Tsukushi becomes nervous and attempts to leave, but ends up staying. She accidentally causes a scene before meeting Kaede.

The F4 try to lie to Kaede about Tsukushi's background, leading Kaede to test her. She ends up confronting her son, who openly admits his feelings for Tsukushi. His sister makes an opening for the couple to escape. He brings Tsukushi to his family's yacht, where he talks to her about his family.

Kaede decides to implement her plans for Tsukasa earlier than expected. Meanwhile, Tsukushi and Tsukasa are spending the night on his family's yacht. She gives him his birthday present. The next morning, his mother attempts to bribe Tsukushi and her parents with money.

Tsubaki becomes more and more worried about her mother's plans for her brother. Meanwhile, Tsukushi has decided to break up with Tsukasa after talking to Yuki. Nishida arrives shortly and brings her to Kaede. She introduces Tsukushi and her son to Shigeru Okawahara, Tsukasa's fiancée.

When Tsukasa storms out of the hotel, he grabs Shigeru by accident. This leads Tsukushi to think that they are already dating. Tsukasa attempts to explain himself to her but to no avail. Shigeru later comes to their school, where she declares her intentions to "tame" Tsukasa.

Shigeru decides to pursue Tsukasa romantically. She confides in Tsukushi about wanting to fall in love. By mistake, Tsukushi ends up agreeing to help her with Tsukasa. Later, old memories of Rui flood Tsukushi's mind causing a slightly awkward exchange.

When Tsukushi breaks things off with Tsukasa, he wonders whether it is time to give up. Later, Sojiro and Akira take Shigeru on a date in an attempt to get her away from Tsukasa, which fails miserably. That night, Shigeru visits Tsukushi to reveal that Tsukasa has asked her to go out with him.

Tsukushi continues to pretend that she is okay. As a distraction, she throws herself into her job. One night, she stops for some tea after meeting Rui by chance. There they run into Tsukasa and Shigeru on a date. Shigeru then invites everyone to her family's villa for the weekend.
