To sum up this series:
K-BL + enemies turned lover + Lot of good kisses

I love when Korean BL have some real kisses instead of pretend to kiss or dead fish kiss in them.

This series has lot of such good kisses which I appreciate but then I remember the last episode kiss which seemed forced to me and hence I didn't enjoy them frankly (of both leads).

The plot and acting are quite good though there was lot of things they could have done with such amazing story line.

I would point out that the editing seems bad coz some scenes are as if the beginning of them were cut down while some seem too rushed.
The direction could have been better given the good star cast.
It was as if some amateur was taking up his first project and failed here & there while trying to complete his assignment.

There are lot of things to complain like the unnecessary dragging of second lead's storyline when all they had to do was to sit and talk it out or how one of the main lead is always running away from another but ends up kissing him passionately the next moment which breaks the link of his character.

But still you will enjoy watching this one and won't regret it. So I recommend you this which will satisfy your BL cravings in a good way.
