I really don’t want this story to ended up as tragedyy ╥﹏╥
based on the author's twitter and side art, I don't personally think it will have a sad ending. However, realistically, a relationship that started like that I don't want to affiliate myself with. But this is fiction and also (even irl) it's their decision and we're only side viewers (I think this is the correct term?)
So if they decided to be together, some fans will get angry, others will be happy. But in the end it's the two characters choices (or rather the author's choice XD, but again removing the author from the equation)
If they managed to end up in a healthy ending for both of them, then this is by far still a lot better than many other Yaoi mangas out there (looking at you fucking omegaverse and the rape justification tropes). (￣∇￣")
I agreed with you (●'◡'●)ﾉ
So the next story development would probably be where he finally decides to let go of Nakyum, realizing he had hurt him so much, and thus the best thing to do is remove him from his life.
Though, if the story requires them to end up together, Nakyum would probably refuse to leave? Realize his love?
I don't see any other turning point :/ or if the events could go differently. I just can't see seungho deciding to ask nakyum to stay with him, he'll probably ask for forgiveness but nothing more
