I haven't read the chapters, but the art style and the gender bender tag really remind me of Boy Meets Girl (BMG). I was curious why there's a gender-bending tag when both guys are so masculine. Then it reminds me of the main couple of BMG. Both guys are masculine too, but one has a vulva. I was right when I saw the author's other work, LOL!

This is a Korean spoiler that I just Google translated into English version. You can correct it if you know some spoilers.
Representative Jang (Seme) had never experienced love before meeting Yeo-won (I think this is the Uke's real name), so he felt that he was unable to express his love in its true form and that he was expressing it through possessiveness in the form of 'getting drunk', which he was familiar with.
Jang monitors Yeo-won's every move, tries to keep Uke completely under his control, and hates him having contact with anyone other than himself, showing the typical features of an obsessive maniac. Even when Yeo-won was at Royal Golf Course and when they reunited afterwards, the only thought in CEO Jang's mind was 'to take full possession of Yeo-won.
Yeo-won broke his promise and ran away. CEO Jang said that once he broke his promise, he would cut off Yeo-won's finger as a warning. It was not a simple threat; he would actually cut Uke's finger. In fact, even when he was at Royal Golf Course, Ceo Jang talked about his past with his finger and indirectly warned Yeo-won that if he tried to run away, he would cut off Yeo-won's finger. However, when he sees that Yeo-won's finger is a mess and his fingerprints are covered in blood, Ceo Jang becomes embarrassed and angry, asking who did this (the uke probably got beaten by someone; it's just my guess).
When Yeo-won, who ran away, says he has a favor to ask, Ceo Jang calls him shameless for running away, but he eventually grants his favor. When Yeo-won asks him a favor, he never fails to do so. There are times when CEO Jang stubbornly says that this cannot be done, but in the end, he listens to everything. In the first part, he was subtly a pushover, but in the second part, he is openly a pushover.
After finding out that CEO Jang paid Yeo Won's debt on his behalf, he becomes furious when Yeo Won tries to pay the money back to CEO Jang.
Although CEO Jang is angry at Yeo-won's unwillingness to change their relationship, he steadfastly pushes his emotions and tries to win Yeo-won's heart by demanding that he give up his heart completely. Every time Yeo-won suffered from a nightmare, Ceo-jang was there by his side, hugging him, comforting him, and clumsily trying to comfort him.
From the way he reunites with Yeo-won, or the way he obediently listens to Yeo-won and provides for him, we can see that at a critical moment, CEO Jang's desires such as possessiveness, monopoly, and desire for destruction give way to the emotion of love. He calls himself a villain and occupies a superior position on the outside, but whether he knows it or not, Seo Yeo-won becomes the standard for all his actions.

Based on Korean comments, there are parts 1 and 2 of the story. I'm not sure if they were season 1 and season 2 of the story. According to Korean novel spoilers, Part 1 was traumatizing, like we know from the Korean webtoon adaptation. Seme was really a possessive psychopath and sex maniac. Part 1 was all about the sickening experience of the uke on the royal palace golf course and ended when the uke decided to run away from the seme. Then part 2 was when they were reunited again. Honestly, when I Google translated the Korean novel spoilers, I doubted if I was reading the same story. I think in Part 2 of the story, the seme is still a possessive bitch, but he learned to help the uke, and he no longer traumatized him (I don't think this will be considered a redemption arc for seme because it didn't give much detail about how he improved his behavior towards the uke, just my opinion).
Damn, this has 70 page comments.
Btw, I think the blond dude was an adopted child and when jaewon died. The parents made seo-in be the replacement.
Yes! I think they hinted that in the previous chapter. Thats why when the incest is introduced to us we can just say they weren’t REAL brothers. Because we all know it’s coming!
If I remember correctly didn't the grandma actually say something about them not being blood related? Still, growing up together as "brothers" I think counts as incest, but they love that loophole!
This has 70 page comments because when only promo was released many idiots were calling it cliche/bad story or shaming other people by saying who read it got bad taste, even calling author unimaginative/uncreative and whatnot.... so people were defending it to at least judge this story after 10 chapters or at least give it a try and not bash it by only reading promo and now same people are drooling over it
Lolz good art and a blond top will do that to a fujuoshi
True!!!
