Mathematics is hard, yes, but there is something with JB that is harder. As hard as he tries to focus himself on his homework, he can't seem to give his all attention on doing some paper works. It was definitely a wrong idea to ask Yugyeom, his brother's best friend, to teach him his algebras. Now he have to put up with the cramp space of his room, a single study table they share, and the time they would be stuck with each other.
