Excellent plot. Superb acting. Heart breaking. Very relatable. Every one of us, at one point, will let loose and let love and it's one of the most wonderful feeling ever created by God. There will be no great pain if you did not love greatly. Once we felt the excruciating pain in love then it means, we love deeply and crazily and I think its the best love amongst all.. loving despite of pain. Both Oh Haeyoung and Park Dokyung showed the immense pain of being left by the one they loved. It also show that evevery one of us goes through something. Everybody is just trying to live of what they have. Everyone has their cross to carry and different methods to cope up with pain and reality. Its a very nice kdrama. I have heard of this when it was still airing but since it was very popular, I though it was just hyped but I was wrong. It's a nice watch.
