he only had non-penetrative sex with the other guy? lol that's so bs

That's the manga trope. The uke will forever remain virgin for the seme even if he is a prostitute.

Ps. I haven't read this manga but I can already see where it is going

Right??? That was so stupid. It's clearly just a way for the author to make the seme jealous while mantaining the uke "pure" for him because WHY

frrr he could've slept with those guys and still be with the seme, what's with them being obsessed with the idea of a "virgin" uke
