if you want to watch one shot series, i recommend this. I understand why the scenes are predictable, its because it's based on a true story. lee jong suk and shin hye sun they did their best to portray the characters specially hye sun-shi. even if it's predictable, there's really something that will tell you to keep watching, I also don't know what it is. but one thing for sure I don't regret watching it, and the ost's are sooo good it makes me cry over and over again.
