Thats how I feel, this whole chapter and the last chapter I didn't see him properly apologize. Sungho was basically like, "lmaoo I almost killed u over a misunderstanding my bad, do u wanna have sex now." But maybe its just me who saw it like that since most of these comments are praising him for him "Amazing character development" ┑( ̄Д  ̄)┍
I completely agree with you, it's was so fast that I can't think of it as a development! I think he's just desperate not to lose this man, that he's trying to act nice. But I can't stand the fact that he didn't say: so, I'm sorry I hurt you, it was my bad I did horrible things to you, I'm trying to change so could please forgive me for all the shit I've done until now? Or something like that.
I'm concerned not for the fact that he changed really fast, but for the fact that he didn't even apologized properly by what he did in the past. In the beginning I was hoping for him to change and realize how bad he was, but now I kinda feel that it's better if nakyum end up alone. I don't know, I feel like this messed up and possessive love ain't working for them anymore, because seungho acted like a fucking asshole all this time. It's complicated because I feel like I should forgive him and wait for him to change more. I know that this story is based on rape and toxic behavior, but it's quite complicated to forgive him that easily. (⊙…⊙ )
