Dou kyu sei – Classmates(同級生)

Licht Sajo is an honors student who got perfect scores in every subject on his high school entrance exam. Hikaru Kusakabe is a guitar player who is wildly popular with the girls. The two would have never crossed paths if Licht didn't agree to let Hikaru help him practice for the upcoming chorus festival. The two soon become friends, and maybe something more.
