Uta (who has newly come out as gay) and Ryo (seemingly straight) have been living together for a year and a half. At first, they had their fights. They also slept together. But these days, they're as tranquil as a middle-aged married couple. Only problem is… they haven't had sex or kissed in almost a year. With their lease renewal hanging over his head, Uta is wondering if it even makes sense for them to continue this way. Why would a gay man and a straight man who aren't dating or even sleeping together keep living like a couple?
