First couple of episodes were okay but gets way better until around episode 13 where it goes slightly downhill except for the last episode. Satisfying conclusion and Sang Tae, lee sang in, moon young, and jae soo carried the show hard with their acting skills. Especially sang tae, who is a god like actor in this show. Reason why this is not 5 stars is because of too much staring, plot is not consistent, and villain failed my expectations. Other than that, its super good! Not as good as crash landing on you but it is very close!
