my fave psychological love stories + others

whenever i think of this manhwa, i ignore the ending (it was just to hasty for me-- i don't like happy endings in these genres). i loved chapter 23 especially; when mc says "at first, i cried from shock, this time i'm crying because i'm so angry that i'm weaker than you". he's an interesting character who kind of just accepts what's going on passively, yet unhappily.
