When I saw the trailer, I honestly didn't care enough to see it, I mainly looked at it for the cast, but I have to say it was a great decision because from the first chapter you get stuck in the story.
It is a drama with only eight episodes that when you finish it leaves you wanting to see more and waiting for a second season.
All actors are extremely good at making you feel the same as they causing you to get excited about what happens to them during the drama.
The characters all seem very characteristic to me, it is true that initially Kim Jo Jo seems a bit cowardly about the decisions he makes but I also understand that at that time he was very young and was not in the best personal situation, in addition to that we can observe how he regrets the decision he makes.
If I had to describe Hwang Sun Oh, it would be immature, mainly because in moments of drama you really think about how he might put himself in that position with what he did to the friend, besides he seems to be a very loyal person.
Lee Hye Young is the best character in the whole drama, he is such a good and forgiving person that he mainly considers the feelings of the people he wants and takes a step back, I sincerely hope that Kim Jo Jo stays with him.
The characters that I clearly hated were his "family", seriously there are chapters in which you want to break their faces, on top of which they are super brazen. The poor girl kills herself by working to be fucked later, really I was angry at those moments.
In conclusion it is a great drama that you have to see if you like drama and love triangles, I hope there is and QUICK THE SECOND SEASON!
