@i.o. I think you should consider the uke in wolf can't sleep without having s**, so he must have some trauma. He offered the kid to get him someone to sleep with because that must have happened to him when he was a kid too. It's wrong and I hated when he did that, but when the kid tried to confess he liked the old guy, the guy said no and walked out of the kid's life. I'm not saying the guy having trauma is a justification, I'm saying traumatized people tend to normalize those actions that traumatized them and repeat them with others, it is shown in a awful way in the manga Niichan. But yes, some actions were too much on wolf in the cage. I don't have a problem with big age gaps, I like those, as long as the 2 meet as adults, when one of the 2 is a kid it makes everything weird.
