Futaro is hospitalized for a while after falling sick at camp school. He returns to work tutoring the quintuplets, only to realize someone has fallen way behind.
I'm not leaving until you tell me.
Ich weiche nicht von dir,
bis du mir den Grund verraten hast.
No me iré hasta que me lo digas.
No me iré hasta que me lo digas.
Je ne bougerai pas d’un iota.
Non me ne vado finché non me lo dici.
Não vou sair até que me diga.
Я никуда не уйду, пока не ответишь.
