It was okay. The show is a slow burn, like REALLY slow. Its a suspense, mystery, thriller type of crime show. The pacing is slow which drove me nuts but you eventually piece together parts to make a whole. By slow i mean you see the actions of these characters beat by beat and then they stare at each other (esp the girl) for a long time with the same angle and I'm at home like "umm...okay?? Say something!" I've watched Japanese films that value static chemistry but this was just too much it was irritating. Not much happens until the end of the episodes.
The only thing I didn't get was that the FL had no real motive to go that insane against him. There was really no personal connection, just a crazy rich chick. I didn't understand her motivation and felt zero sympathy for her. BUT the ENDING was SO satisfying. Thank gawd for that one character (you'll see who). Is it worth watching? Its meh. But if you're curious, go for it. The male lead is pretty good.
There's also a lot or random, useless people in the show but I enjoyed the friendship the ML had with his community.
