Well, the actors are really interesting since they have new roles to portray far for previous acting. It's visual is admiring and chemistry even for young roles is indeed nice. The OST also complements and creates wholesome mood. The flow of the story is clear and logical which fascinates the viewer to watch more and look forward for next twist. I am a fan of SF9 Rowoon, so I will definitely support this since he is becoming good in acting with a great actress Park Eunbin. This story triggers my interest on how it will run and end.
