Long Period manga volume 1 features art and story by Nagisa Furuya.

Yusei insists he hates his best friend—or at least, that's what he tells himself. Itsuki, his gifted, charming, and impossibly talented friend, seems to be wasting his potential. After all, Itsuki could easily get into any prestigious university or join any sports team, yet he chooses to spend his time with Yusei. Struggling with feelings he can't quite understand, Yusei pretends to despise Itsuki, hoping it will help him overcome his emotions or, at the very least, distance himself from the one person who means so much. But is pretending enough to change Yusei's heart? And what about Itsuki's feelings?
