Nishikata doesn't know what to write for his calligraphy class, so Takagi-san suggests they should both write what they want from each other.
Nishikata wants Takagi-san to stop teasing him, of course, but what does Takagi-san want from Nishikata?
You have ink on your cheek
هناك حبر على خدّك
Du hast Tinte im Gesicht
Tienes tinta en la mejilla
Tienes tinta en la mejilla
TU AS DE L’ENCRE SUR LA JOUE
Hai dell'inchiostro 
sulla faccia
Você está com tinta na bochecha
У тебя чернила на щеке
