One of the best love story I've ever watch. Start watching it now and don't hesitate. I finished it in 2 days which is kinda rare for me lol. It's that good.
Just finished this drama, 10/10 easily. What I noticed instantly is that the action in this drama is so realistic. In other action series/movies the leads are untouchable and most of the time unscathed. Start watching it right away and don't hesitate.
