I absolutely loved this drama. ML and FL has amazing bonding by the time drama finishes. It's filled with mystery and thrill. There no overt romance as per say, but they are a couple it is showed in their emotional connect.
FL loses her brother. And it's her journey, finding who killed him. She also suspect the ML of it.
He also has his owm back story. And a troubled past. I loved his acting and character potrail. Oh, and he is good at fighting. The action scenes are good, but can be brutal for some to handle, so be warned.
Watch this. Really really. I came out having more than I expected ?
