It does work like that, you need to reread the first season because you could see nanjo was hesitant yet did have feelings for mokyeon. He actually did kiss mokyeon back on chapter 29 and initiated their shower sex chapter 24. I think it was his feelings for sunhwa getting in the way but that’s all gone now. Author didn’t rush the story either. It was all planned out from the beginning and it was originally supposed to be a novel.

Bro I feel like I'm the only one who is spazing out rn. LIKE WHY WOULD NANJO WANT TO HAVE SEX WITH HIM AFTER AVOIDIG HI M FOR SO LONG. Its just not making sense to me AT ALL.
