This was the first experience of watching an ongoing K-drama for me, and honestly, I was not satisfied. I think it's better to watch a good drama than just experience watching ongoing.
First of all, the main characters were not attractive to me; they didn't even play well in my opinion.Ji Won was not friendly and loveble enough. Ji Hyuk was very overrated and his charm was exaggerated, while he was very ordinary and had no charisma. The love between these two was soulless and artificial.
Song Ha Yoon was the best.She played very strongly. This difficult role and its psychological characteristics were real and attractive. This is perhaps the only positive point of this drama that was able to show the fact relatively concretely that sometimes your biggest enemy is a reliable close friend!
Min Hwan's character was almost well designed; a combination of naivety and meanness.
The whole story seemed to be empty, and from one point on, it was not clear exactly what the issue was, and I prefer not to say anything about the other two couples in the story!
