I mean its not like hes explicitly shown to be into women either, I think the whole point is that hes not used to intimacy or romance in general bc hes spent his whole life alone and scared of ghosts. Would a Truly straight man jump immediately to "im in love with you can we date" with a guy he wanted to be close to? He even said just being friends was an option that didnt immediately occur to him lmfao. I agree that the romance isnt super developed, but its a 7 chapter smut manhwa. Literally anything whether it be gay, straight, lesbian would not have a strong romantic plot line
The more I think about it the more I really do think it was just a moment of fear and internalized homophobia rather than him being "turned gay". Bro literally has posters of a half naked woman AND man, and also clearly had no aversion to making out and being groped by his bf. It's assumed hes never had sex before, and he had a traumatic time in the military surrounded by rough and tough guys that likely were also homophobic. I also think that scene where the guy was asking for a mop while bullying the other was for.....not great reasons. I genuinely think he just panicked once sex was on the table. It also served as a device to force him to be honest abt the initial reason he approached him which led to them being closer after making up.
Crazy cuz if anything i would assume this author might be a gay man. Literally name how many manhwa u can find where they have body hair he had arm and leg hair, pubes, and a beard. U never see that in manhwa. Also this isnt ur normal turning gay trope cuz he wasnt interested in anyone before bc of the ghosts yea i prefer when they just say theyre gay but this is a really different case

I would assume the author's not actually a gay man, probably not even a semblance of queerness because how do you just turn gay? It's clearly portrayed that the black hair is not into guys but one episode later he's suddenly ready to have butt sex? That's not how it's work babe, really disappointing. I know yaoi manhwas are mostly fetish content for straight girls but I can't get past this. Does anyone feel the same way?
