Most disappointing k drama I have ever watched

I don't usually do reviews but I am completely frustrated with this drama, I have been watching many k dramas and I love the chemistry between the leads but this really broke the myth of k dramas. I literally couldn't stand any scenes of the leads. It shocked me. Of course its your choice but I feels its best you not watch the useless drama. But I must say Kim seon ho was marvelous and he gets the 9 stars! I loved the side couple to Samantha is a classy babe, wished had more scenes of her as well.
