Meanwhile, Song Kang went through audition competing with 900 people and got casted.

Each space decorated as if the app function in the drama is visualized in reality and gives a romantic experience to lovers, friends and family who visited the place. Moreover, an app has been released for the promotion events, that looks like the one in the series, but works differently.
