I kinda don't like the FL..

I like the part that reveals everything about the ML that he is just misunderstood.. He just don't want his family to get destroyed because of his painful past.. He hides his true self because it is the only way he thinks that doesn't make the FL doubt about him.. but clearly in the flashbacks he indirectly tells her that he isn't a good man as she think he is, something like that.. But she still nags him so in the end they get married. So yeah this drama is good if it wasn't because of the FL. I felt like she doesn't love him enough to trust and believe him.
