I'm sorry but the new volume seems machine translated, a lot of sentences don't make sense, if you compare it to the first chapters it's such a loss because it also removes personality from the characters, Yamamoto was so funny before.
Also they seem out of order, they were having sex in the small soundproof room in ch.1 of the volume and later they first introduce Yamamoto to said room.
Both of the guys in the couple have pretty muscular bodies but it is not bara I guess. The uke has brown hair and the seme is blond. They never had sex, its very shounen-ai. Seme is like a sales representative at this company that does something related to insurance. Unfortunately that is all I remember Σ(  ̄□ ̄||)
Anything else
Anything else you remember where it is mang or webtoon new or old

I think seme shouldn't even entertain Jiho (Blondie rapist)
He just agreed to meeting him again for drinks, and based on his reaction to the group chat it's very common for them to rape people, and he walked around with them so this already makes the seme a lot worse for me, and he wasn't very nice to begin with.
His past of suffering doesn't erase the scumbag fuckboy he is/was.
Sure the uke was being very naive and maybe stupid but seme is the one that hangs out (or used to) with those bastards willingly.
