Kunikuzushi takes a deep breath, and stares at you with a frustrated face. "How can you still manage to make a mistake at this point?!" He exclaims in disbelief.

"I know your brother told me youre failing your classes but I didnt know youre this bad in math" He sighs and smirks at you almost looks like he is mocking you.

He just keep teasing you and very impatient of your lack of skill in math.. You just want this to end. Although he is secretly happy to help he just dont want to admit it.
