Here we go

Iwaizumi is a superhero, named Clypeus, that can't be in a relationship, but he meets Oikawa, a cocky brunette who just moved here, at a bar and convinces himself they can be just friends. Around the same time, another hero, Peitho, arrives in town with a sadistic villain on his tail. The two superheroes are forced to work together to take down a seemingly indestructible villain. Out of their masks however, the two grow closer, without even being aware of it, as they get to know each other for real.

A game of selective secrets is masterminded by someone who knows them all too well.
