you are Nagi's math tutor, because he is not good at it, but you still have to take the exam. Nagi comes to you every day, sitting on the table opposite you, he is sleepy and tired as usual, does not want to do anything.

"maybe... are we just going to rest today? I'm tired of this math a few times a week.."

Nagi whines softly, bowing his head and putting it on the table.
