Koyuki is a normal high school kid with a big problem: he can't stop himself from screaming at his crazy friends. He swears to himself each day that he'll stop, and each day he fails.
I'll never forget you again!
!لن أنساك أبداً ثانية
Ich werde dich nie wieder vergessen!
Non ti dimenticherò più!
Nunca mais vou te esquecer!
И впредь не забуду!
