I agree, though we aren't discussing whether he should be around young adults in general, we're discussing whether or not he should be around Seunghee specifically based on evidence that implied he might actually have feelings for him. Yes, he has preyed on others, but would you rather him to continue or be in a consensual relationship?
I think you're mixing them up.
You really don't have to prey one someone innocent in the sense of wanting to manipulate them in a relationship for it to be considered ephebophilia. It is also possible to like/fall in love with someone in that age group without those underlying intentions, and still call it ephebophilia.
Don't forget the possibility of someone preying on that age group for the sole reason of abusing them mentally/physically, is possible with no sexual attraction. Cases like that are not ephebophilia.
Also, unlike pedophilia and hebephilia, age gap has actually nothing on ephebophilia. Anyone at any age can have that sexual preference for that age group (15-19).
The term ephebophilia is not the only term of it's kind. There are terms for sexual preferences for adults (teleiophilia) or more specific middle aged adults (mesophilia).
Pedophilia, pedophile, pedophilic... I had to search it up as I was hesistant to use it for this manga, and man did I learn a whole lot today.
Pedophilia, is first and utmost described as a mental disorder where the adult is only/primary sexually attracted to pre-pubescent CHILDREN. Specifically ages 13 or younger.
Hebephilia, a term not many know of, are used for adults that're only/primary sexually attracted to pubescent children (age 11-14). Strangely enough, hebephilia is not considered a mental disorder in the US, as the US does not follow the international classification of disorder (ICD).
And then there is ephebophilia which, unlike the above, is not a mental disorder, but a term used for the sexual attraction to mid to late adolescents ages 15-19.
Do keep in mind that anyone age 16 and up and that are at least 5 years older than the PRE-PUBESCENT CHILD, can be diagnosed with pedophilia.
Blond uncle is not a pedo, okay? Seunghee is not a pre-pubescent child. He's (almost) a young adult, and regrettably just as much at fault as the blonde uncle for being in that kind of relationship.
Call it a preference or a extreme fetish if you may, but it's not pedophilia. ┑( ̄Д  ̄)┍
