The story and acting skills of other casts are supreme, 9/10. except for the lead female. BAD. I don't know how she gets the female lead. Even towards the end of the drama, where the male lead and female lead should fall for each other, I sense no romance feeling given out by the female lead. It's like a kid acting with adults who the acting skill level is not on par. I will totally rate 1/10 just for her acting skill.
Otherwise, else is great. The story is about a clumsy girl with a smart and cold male lead, where the male lead helps the female lead whenever she is in trouble.
