Firstly, the story line of this series is really AMAZING.

The first episode is so awesome. Gun's acting skills is no surprise anymore. He is just AWESOME . In just a episode, he displayed several kinds of emotion in the needed scene.
And Off ( Sean ), his acting is 💯 GREAT. The tone of his voice corespond to the expression of his face. He is so handsome and his acting is great.
In just one episode, we can feel their chemistry already.

The OST is so...The lyrics keeps breaking me down. 😭
This series is AMAZING.. Although, I feel a big twist is waiting for us. I Just hope they don't break my heart.
Everyone else in the series is playing their role greatly. Great job guys!!
