I can say this drama is good. You can watch this drama to spending free time but i could say there isn't a big conflict on this drama? i mean there haven't complicated problems/plot. the main male lead admirer doesn't try hard to destroy his relationship and of course the main male lead is so consistent and so firm on reject "his admirer"
The main male lead is realistic (maybe because he lecturer? idk), cute, but not too romantic. he is "cold boyfriend type"? but i can say he so lovely because he try to be romantic boyfriend for his gf, lol, AND THE MOST IMPORTANT IS HE IS HANDSOME AND SEXY. (first ep will make you exited) haha

The main female lead is pretty, she good at acting and expressional. She remind me of a korean actrist (idk her name but she was on "My ID is Gangnam Beauty" drama) i'm right?

At any rate this drama isn't bad. the side story which is the main female lead's sister and friends is such a good things but unfortunately i cloud say that they're not good looking as far as the main lead do. (I'M SORRY)
