On chapter 36 and i really don't like Chungi. He was amazing as only a fuckbuddy. I don't like the development where he has feelings for mc and is acting like a complete douchebag?? It's so uncalled for idk. He was such a fun character and I feel like now his character is completely ruined for me. Although I am curious about mr an and his dynamic but otherwise I don't really see myself liking chungi at least until he stops being like this.
