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.

rather goof off than study!
هذا ما يفعله الأطفال عندما يتكاسلون

wenn sie lieber rumalbern, als zu lernen!
¡Eso es lo que hacen los niños!
¡Eso es lo que hacen los niños!
T’es le cliché du cancre

Questo è quello che fanno i bambini
quando perdono tempo invece di studiare!
É o que crianças fazem quando
preferem brincar a estudar!
Дети как раз так от учёбы и отлынивают!
