## Summary

Akatsuki approaches Yume and asks her if she wants to walk home with her, but she declines. Akatsuki's friends then chime in and claim that Yume has a lot on her plate since she's aiming for first place in the upcoming mid-term exam.

At home, as Yume studies, she recalls back in middle school being bested by Mizuto in a math test she was academically best in. Hence, Yume assiduously studied to reclaim her spot in the 1st place position, and despite doing so, Mizuto didn't care. This made Yume feel hollow and unfulfilled by her accomplishment, believing she had an unrequited rivalry with him. It was a chance meeting in the library that she'd fall in love with him after talking about mystery-themed books. Later confronts Mizuto, who doesn't seem to be studying much; however, he claims that he'll steal the top position from her in the upcoming mid-terms. To that declaration, Yume claims he can do his worst.

The following day, Yume yawns aloud, and Mizuto comments on Yume's determination to keep her top position in the school. Yume brushes it off, claiming it's her life to maintain her position there. After the first day of exams, Yume reflects on her test score; however, she worries that Mizuto may have scored higher than her because Japanese is one of his academic strengths. So, Yume enters Mizuto's room, finds his test, confronts him over how he left the last answer intentionally blank, and calls him out for holding back for her sake. Their mother then intervenes and leaves to fetch their father to help mediate the situation. On the other hand, Mizuto stands his ground, claiming that he doesn't have any interest in being in the first place in the midterms, and Yume can think of him any way she wants. The comments made by Mizuto cause her to cry and later return to her room, believing she did have an unrequited rivalry with Mizuto.

Eventually, the mid-term results are made public, and as it turns out, Mizuto made first place, and Yume made second. After her conversation with Mizuto and then Akatsuki and her friends, Yume realizes what truly "defines her". Upon this realization, Yume cries tears of joy, and Akatsuki tries to console her believing her tears were the opposite.

Afterward, Yume catches Mizuto meeting a new girl in the library and uses the same pick-up line he used on her. The girl was named Isana, and the two of them talked about various things like the definition of friendship. As it turns out, Isana was already a friend of Mizuto and the only person he clicked with. Afterward, the two run into Yume and Akatsuki at the school entrance, and Isana is formally introduced to them. Once they're gone, Isana is informed of Yume and his relationship together.

At home, Yume reflects on her past and current relationship with Mizuto and acts kinder and more cordial toward him for dinner the next day. Yume's actions perplex Mizuto, and he relays this to Isana, stating it's not that she's being distant; instead, he doesn't feel annoyed talking with her. Isana then reluctantly gives her advice to Mizuto about his situation and goes on to say that everyone has their own set of criteria. Like a base model of what a person would want or like from another, and Mizuto appreciates the advice Isana gave.

Eventually, in her room, Yume relishes how good she feels now that she's over Mizuto, and he visits her. Mizuto then confesses how he dislikes how she's been acting toward him as of late and demands to know what triggered it. Yume then confesses that it was Isana who triggered the changes in her personality, which Mizuto is relieved over, but comments as he leaves her room that it was "creepy".

The next day at school, Yume, accompanied by Akatsuki, formally introduces herself to Isana, who is taken back by this sudden introduction. Mizuto then informs Isana of Yume's misconception of their relationship, and Isana gives an abstract answer that reinforces that Isana is not interested in Mizuto.
