Maybe he’s not as bad as we think? He’s not born bad, it’s all because of this shitty father of his. As for the brother, he wasn’t a good people too, he’s like the father, and he killed him to somehow get a revenge of his father. For his dog, I don’t know (well, I don’t even remember the dog, haha), and for her sister, she’s totally unlike him, the chairman doesn’t hate her, doesn’t treat her as he treat Sangmin, and her “kindness” wasn’t supportable by him.
For our MC, if he wasn’t that perfect, if they didn’t work in same hospital, Sangmin wouldn’t have all the pressure from his father, and wouldn’t be like this, they could be very good friend, as in high school.
(Sorry for my broken English, hope you can understand )
I think the chairman is behind everything, and somehow LSM know it, and in his way is helping Kim Jihyun by asking him stuff.
