Kabukicho Bad Trip: Ikeda and Rio

Café manager Ikeda is highly focused on his job, but one of his regular customers, the flaky host Rio, always ruins his day whenever he drops by. The way Rio acts reminds Ikeda of someone from his past who he'd rather forget, so things would be better if he would stop coming around. But one thing leads to another, and Ikeda ends up spending the night at Rio's place! Neither man has any intention of getting serious anytime soon, but they may find that the best way to get over their respective past traumas is to open up and face them together...
