Jang Ki Yong is a great actor. The very emotional Responses show it.

We know the writing could have been better. The ML and FL both struggled with the realities of life in a long distance relationship.

If you want to see Jang Ki Yong in a much better drama "My Roomate is a Gumiho" just started on iQIYi. Just a few episodes in and already seeing some character development. FL is extremely funny and was surprised by the comic tone of the show at times. Goblin like vibes here and there.
