When Honda spots Miharu having a friendly conversation with their classmate Sanagi Nasa in the waiting room of a hospital, he decides to investigate Sanagi's identity and his relationship with Miharu for the sake of his best friend Mishima.

Meanwhile, Mishima gets caught in the crossfire of an argument between the track and field team and has been called to the student council room, where he is standing before third-year and student council president Nakajima Mikado and his friend Sakurakoji Masamnue alongside second-year Asumi Natsu.
It's a senior's responsibility 
to look after his underclassmen!
مِن مسؤوليّة الزّميل الأكبر 
!أن يرعى الزّملاء الأصغر منه
Dass die Älteren auf die Jüngeren achten,
ist selbstverständlich!
¡Siendo mayor
debes preocuparte de los menores!
¡Al ser mayor
debes preocuparte de los nuevos!
C’est normal que les anciens
s’occupent des nouveaux !
È compito degli studenti più anziani 
badare ai più giovani!
É responsabilidade dos veteranos
 cuidar dos alunos mais novos!
Как старшеклассник, ты обязан 
присматривать за младшими!
