dude, seriously. yuki can't even have a word of what he wants because the other dude has his head stuck in his own ass. he himself has a fetish, why can't he at least try to understand yuki? i don't remember much of vol1 but i remember yuki asking him to be hurt and the other guy said he would do it, but in the end he didn't. in a relationship you have to try make things good for both parties, but he doesn't respect it. if he likes yuki's face, there's still a full body to hurt. they can make it work, but he's still thinking only about himself.
the problem about this manga, it's that the author tried to make yuki's fetish a bad thing. it's just kink shaming. i hope they can understand each other's fetish and work in giving pleasure for the two of them. only like that a relationship can work.
that face-con guy is so annoying. seriously, so annoying and selfish. he doesn't give a fuck about yuki, he only care about his own desire (yukis face). if he really liked yuki he would at least try to understand him. a selfish dude like him should first learn how to be in a relationship
