I have read the novel not fully it was still ongoing at that time... The guy has system that predicts the kind of day, encounter he will have. He also get props for successful mission. Since he was criminal before he knows how the system and people work. So along with system and previous life knowledge, he solves lots of cases ofc in his own violent way. He is a scumbag too.. trying to get money from high schooler in exchange for acting as her father and allowing to stay upstairs of their shop, asking for sex when he catches sight of female boarders in the opposite balcony and he does sleep with her... unscrupulous is him, It is realistic in the sense people wont change overnight or in single reincarnation... Lot of things you just wanna punch him in face for... It will have lot of sexual innuendos I'm sure if it follows the novel but we do have a female cop who is strong and they form a team...
