Koyuki's worried about his future. He wants to be a teacher, but he's not sure he can do it.
The back of my head really hurts!
!مؤخّرة رأسي تؤلمني حقّاً
Mein Hinterkopf tut höllisch weh!
¡La cabeza me duele mucho!
Mi fa malissimo la nuca!
A parte de trás da minha cabeça dói muito!
Затылок раскалывается!
