A little too slow at times but overall an entertaining read. The MC isn't and idiot and her interactions with the ML and their power dynamic are pretty realistic (by webtoon standards). The ML gradually becomes more obsessive over her (and I love desperate MLs), but he's pretty jerkish in the beginning. If you don't like long reads or just want to get to the good stuff I recommend reading maybe the first few chapters, skipping to the 20s, and the skipping to the end of the 30s and reading from there. You'll be able to understand most of their history and relationship by then. If you're an especially comprehensive reader just skip to chapter 40 for the "meat" of the story. The side stories are nice and flesh out their relationship by adressing some of their insecurities and worries, but it's at the expanse of B plots and C plots that either end up going nowhere or are just confusing in general.
