Read up to chapter 18 and uke has no remorse about his cheating tendency, keeps fucking with his HS crush everytime they meet. Sebin is a nice guy but a cuck, he got mad when he first saw the kiss mark but he gave in to the uke really quickly...basically he lets the uke step all over him. HS crush seems to have liked the uke since HS, way before he saw the uke going down on the art teacher but even though he's sleeping around with the uke rn, he himself is fucking another guy...guess who it is??? It's one of the uke's friends(blonde) who was bartending when he first told his gay friends about him cheating. Not just that but those same friends don't give a fuck about his cheating and even helps him hide it. Basically, every single character in this series is irredeemable human trash. Not worth spending money on.
