"I did a lot of thinking after that. He told you that a girl will put up with a lot from her boyfriend, didn't he? Maybe I was putting up with a lot from him, too. If something as minor as this caused a rift, our relationship was bound to end one day. I guess my head was in the clouds."
Yuki Matsuoka rushes over to Nakatsuka, who has just been punched by Tsukasa Domyoji. Tsukasa storms off after telling Yuki "Find yourself someone better than this." Nakatsuka then claims that he only "put [his] hand on [Tsukasa's] shoulder." Tsukushi Makino apologizes to him, but Nakatsuka dismisses her saying "If you're his girlfriend, you probably let him get away with a lot." He then leaves. Yuki reasons that "Tsukasa wouldn't have hit him for no reason," though she still "wants to believe in [Nakatsuka]."
At Tsukasa's house, Tsukushi bursts into his room where she also finds the F3. She then confronts Tsukasa saying "I want you to apologize." He does not feel he should apologize to Nakatsuka, but refuses to explain what happened and simply says "He made me sick so I hit him." Tsukushi then hits him, repeating his words back to him and claiming "Using violence is not right." Storming out, Tsukushi meets Tsubaki Domyoji who is happy about her dating her brother. Tsukushi reveals that they have broken up.
The next day, Tsukushi is sitting in her classroom still stewing over her argument with Tsukasa. Yuriko Asai attempts to say something to her, but Tsukushi says "Shut up, will you!" Later, Tsukushi meets with Yuki who reveals that Nakatsuka did not go to school and is not answering her calls. Yuki tells her "If something as minor as this caused a rift, our relationship was bound to end one day." Overhearing a couple nearby, Yuki and Tsukushi decide to leave. They turn around to see Nakatsuka with a girl.
