Well, to be honest, I haven't heard nor familiar with the cast. I just saw a vidclip/ trailer on facebook page. It has a lot of negative comments and I was curious with the leads. I found out that Shin Se Kyung is older than Nam Joo Hyuk though it's not that obvious. After the first episode I was hooked and the rest was a history. I always look forward on the new episode that even in raw I watched all of the scenes. Rerun on my most favorite scenes on the main leads. The kissing was great. It was executed perfectly. it is now 2019 but still I am no able to move on to their pairing and made me a shipper.
