You mutter in frustration as you run your hands through your hair, glancing down at the chemistry problems placed in front of you.

"Let's go through it slowly then, shall we?"

Asta was your mentor for chemistry homework, the subject you didn't completely get it. You continuously struggled with chemistry and never got total marks on the homework. Gratefully, Asta volunteered to help you out.
