I truly enjoyed this drama. I'd say first 15 episodes and last 8 episodes were very well written. I got bit bored in the middle but I didn't skip any episodes. I don't think this is super great like some other drama with 9-10 rating but it was pretty entertaining and main CP did great job performing and 3 other CP did good job while many dramas usually have boring stories for second and third couples.

The last 8 episode had unexpected twist and turn and ML made me cry at Ep 37. He is quite a good actor.

I recommend to watch this drama if you like couple story how they develop love from love & hate relationship in the beginning and solve mysteries round these couples.
