Im glad more people agree that them hooking up like this seems unnatural. Like it wouldn't be far fetched for them to get physical in the future but at the current place in their newly developed relationship, it just doesn't feel sincere or realistic. It seems rushed as if the author just wanted a quick way to tie loose ends. This couple had so much potential but I feel it has been wasted by having them have sex so suddenly without any actual chemistry. Jihye doesn't appear to have any emotion towards Gyoon, at least not beyond one of a friend. But suddenly we have to believe he wants Gyoon/ feels possessive towards him? Idk
I wouldn't go as far as saying that Jihye doesn't have any special emotions towards Gyoon. I guess he had his reasons for reacting the way he has when he saw him and that blond guy (forgot his name) kissing. I think he was hurt. Nonetheless, I agree that the whole sex thing is a bit rushed. For Soohwa and Yohan, the baseline was different. It was a bit weird but not out of place that their relationship started off physically.
Soohwa calling Jihye is probably the only thing Gyoon won't bury him for.
Not sure how to feel about it tho. I'm happy for Gyoon but I never imagined them to do more than talking and maybe, just maybe, kissing. It always felt more like a platonic relationship. Them getting physical feels wrong, somehow. I dont know how to express it differently. I hope you get what I'm trying to say. I dont hate it but I don't love it either.
