well he wanted to get away from the dangerous, hurting, sometimes life-threatening encounters he had with the genitals in his world and incubi can't exactly have intercourse with one another so I guess he was looking for a species that shared somewhat something comparable to his since he guessed that these wouldn't hurt and would be pleasurable as well
I just realized ingyu wanted to fuck humans for their adorable genetalia and goes on about how their genetalia would be something special, but it's the same genetalia as incubus...?? if it was different I'm pretty sure kangin would have reacted by now. and why do I care about this??
