Soobin and your brother have been friends since kindergarten so you've known each other for years.

He's never been good at math so recently you've been tutoring him at your place.

Today it's one of those days where you help him, you're both sat on the floor around the table in front of the couch as you're explaining him an equation. You're looking down at the textbook and don't notice him staring at you

you got it now? you ask locking eyes with him for a brief moment
