Yuuma Isogai has a slip up at a drunken party, where he kisses a complete stranger. When he wakes up, all he can remember is the name Hiroto Maehara and his face. Isogai hoped never to see him again out of embarrassment.
Although the world is a big place, people come around.
Apparently, Hiroto Maehara also remembered every little detail from the party. Isogai's soft lips down to his cute little hair antennae. He was looking around to find Yuuma Isogai so he could apologize, but they start seeing each other everywhere, it's impossible to avoid.
Maehara finds himself falling for him.
