Ai Hayase is a second-year student who appears in the anime "Senpai is an Otokonoko: Sunshine After the Rain". On the first day of school, she quickly became friends with her classmate Makoto Hanaoka. However, when she discovered that Makoto was actually male, Ai experienced confusion and gradually lost the courage to speak with him openly. As a result, she and Makoto grew apart.

Following this incident, Ai deeply regretted her behavior and sincerely wished she could apologize for how she had acted. Unaware of her regret, Makoto mistakenly believed that Ai disliked him and had rejected her friendship. This mutual misunderstanding led both of them to close off their feelings about the situation.

The turning point in their relationship occurred during free time on a school trip. The two encountered each other by chance, and the misunderstanding between them was finally cleared up, allowing their friendship to be renewed and reconciled. Incidentally, Ai remained classmates with Makoto for all three years of their time in school.
