Math problems

So high school/college AU with tutor!Mark and student!Jack.

"I'm not even gay.. Am I?" Jack opens new doors he didn't know even existed and Mark just might have found a new source of energy in his life. But something stretches the strings of their friendsip and even some tears might fall. Shit happens and stuff follows.

This one wil NOT have ANY smut in it! ...it's gonna be hard for me so there might be some smol intimacy but not straight smut :3

A cutsie lil' request from @Ash-pie
