Senpai is a nerdy high schooler whose manga work is discovered by some loud girls in the library. They all tease him, but one among them, Nagatoro, takes it further than the others.
You're my senpai, then.
أنت سينباي إذاً
Dann nenn ich dich mal Senpai.
T’es plus vieux que moi, alors.
Allora sei mio senpai!
Então você é meu senpai, né?
Выходит, ты старшой.
