Honestly I always avoid K Romance Drama as I found it too cheesy for my style. I always though "no person in real life does that" or "if this happen in real life it will be scary" but I just couldn't miss on Jo In Sung's come back. He is forever my favorite actor (mainly because I found his looks enchanting).
So I give this drama a try and I'm instantly fall in love with the story and characters!
Jang Jae Yeol is not like your typical K-drama main lead who will do anything for the love of his life. He still keep his composure ,respect himself and the boundary.

I also find Ji Hae Soo's character development after meeting Jang Jae Yeol really good and therefore make her even more likable characters as the story goes. I definitely love their acting and chemistry.
