They run into the ex on chapter 3
does anyone know of this manga where uke sleeps with people only doing it from behind because his ex said some stuff and I think also because he does it with straight men, I forgot how he meets seme, but at some point seme tells him to face him, and also they end up running into the ex while it was raining and he started to say some stuff about uke, and seme started to get angry(not You and I can't do this)
