Koga Nao

Nao's got a quirky personality and marches to the beat of his own drum. Chronic insomnia often leaves him with dark circles under his eyes and a perpetually sleepy look.

Thanks to a misunderstanding with Kirame, he ends up in a situation that looks suspiciously like a one-night stand. To make matters worse, his long-time crush, Yua, suddenly decides to respond to his confession, which he had left hanging for ages. Just like that, he's slapped with the title of a two-timing scoundrel.

Nao tries to roll with the punches, figuring what's done is done, but he has absolutely no idea what to do next.
