I have read most reviews and I think they have reviewed too prematurely. HRZ is a definitely an odd character... too perfect.. in the entire plot but the ending (last ep 30) wraps up beautifully and unexpectedly.. and explained. I'm not going to give spoilers but this show is one of the bests, great acting. It got me chasing ep by ep. I was having mixed feeling for the ML's character but great wrap with happy ending.

A word of advice to all.. dont review before you watch till the end. I hardly write reviews but cant help correcting and adding on. Enjoy the show.
