This drama has a really interesting concept in terms of the scams and spying but I don't like the direction the writers seems to be going with the FL. She is meant to be a con artist but was trusting the police with investigating the ML's death and told them about the ledger. She is also doing a lot of wallowing and the scenes are getting a little tedious as they don't add anything except possibly trying to reinforce the viewer that she did actually love him and wasn't trying to scam him like her friend inferred in one of the earlier episodes.
Overall, this shows has some great reviews but I really struggled to get into it. I really disliked the female lead, Han Yeol Moo, which made me struggle to feel any emotion towards her and her family's story. Due to the the second half mainly revolved around her brother's case, I have dropped this after 7 episodes.

However, not all the shows have such bad bangs like this show does.
