Be patient. Jaeshin is already transforming into a lover boy. I don't want to spoil it for you but if you read the last raws you'll be surprised at how different and careful he acts.
Besides, here's what the creator said about him in her published note:
"Jae-shin may come off as self-centered and arrogant, but he actually is an attentive partner who pays attention to all of Nok's reactions. His interpretation of those might be the problem, though (lol). Nok, of course, thinks Jae-shin is just doing whatever he wants."
I know. I've seen many stories of the seme being "self-centered" and "arrogant", but is actually looking after the uke and watching his actions. We even saw the seme looking after the uke when he was hurt, which was actually pretty cute.
But does that justify seme raping uke? No. Even tho he's not human and doesn't technically follow human laws, raping him to ward off other bad ghosts is still morally wrong to the uke. And like I said, the uke seems to be "falling" for the seme after they fucked in S2. "Why do I keep thinking of him?" Showing that the uke is developing some sort of feelings already.
Like bruhhhh, howwww??? Authors always make the uke so dumb and kinda naive that it's hard for me to feel bad for the uke when he's so simple. I know we all want them to be a cute couple already, but the progression has to be good as well. So imo, it would be better if the uke really doesn't develop feelings for the seme, while the seme catches feelings but uke doesn't reciprocate his feelings at first.
Idk, maybe I just want more drama between them because their personalities are so different and the seme obviously controls this relationship. We see the uke be very vunerable with the seme, like most stories, but we don't see the seme be vulnerable with the uke often. And I like this story, but it's just another trope of "innocent uke and broken seme" where the seme has control of the uke's situation and they later fall in love.
The uke is so cute and I hope he can have a happy life in the future. But that bastard, the fucking seme... I wanna see him SUFFER. Do I want them to be a happy couple in the end? YES! But right now, I want the seme to cry and be in pain so bad bro.
I want that arrogant little shit to be MISERABLE rn. Seme is a cute puppy, and I'll admit, a hot devil at night. But I just want the uke to be in a situation where he no longer needs the seme's help, BUT the seme still needs/wants the uke's help. I'm literally creating my own plot and scene of these characters where the seme becomes useless to the uke and the seme becomes miserable BWAHAHAHASJKHDF
Like, I can't wait to see when the uke and seme have their lovey dovey, wholesome moments. But I'm so fucking tired of "uke depending on seme and only the uke is actually helpless/miserable" trope. And I feel like the uke is falling for the seme too fast!!? At the end of S1, uke was still wary and kinda hated the seme. Then beginning of S2, he's falling for him pretty quickly after they fucked?? Like, the uke gotta be headstrong if he doesn't wanna keep being used by the seme like this.
But if he's falling for the seme this quickly, sorry, but he only has himself to blame if he's played and thrown away by the seme The uke really gotta make the seme work for his love and has to kinda break the seme's heart a little before they can actually be in love.
