I love everything about it! The casts, the plot, the edit, and the ost are all on point. I can't imagine other artists doing the role other than them. It's so good that it gives me butterflies in my stomach every time I watch it. It also has a mystery that made us come up with different theories every week while waiting for the release of each episodes. It's giving a vibe that you want to rewatch without cringing. 10/10. I fell in love with Byeon Wooseok already. I hope I can find my own Ryu Sunjae. If my love story doesn't turn out this way, then I don't want it, lol
