I enjoyed watching this show from start to end, it's rare to see a drama getting better and better with each episode, characters in the show are used well they are not in it for the sake of it, cast did well especially Lee Joon gi was at his best in this drama.
Relationship between ML & his family, his sister and fake mother in the sense some scene we feel she is actually the mother she even had a good interaction with Ml's daughter, it was hard to say one character is pure evil except the real baddies in the show. Even that cop character ie friend of FL he was interesting his character was not in the show for the sake of it, each character in the show that is important to the story were used well.
I enjoyed it so much watched it 3 times and still planning to watch whenever get time and feel to watch.
