I really enjoyed the first 2 chapters. And how the FL punishes the cheater and not the girl he was pursuing. But I did not like that Sykes-Martina arc where the fiancee is just a crazy bitch who punishes the girl. I liked that the GO really just didn't give a fan about it in the first place. It was always just a game.
