This show is not your typical kdrama, the story is dark that it surprises you in every episode! I feel uneasy every episode that is why my Rewatch value is low. The OST really fits the scenes, every time the OST plays it gives you chills because it’s really good and Lee dong wook I must say, he’s really good. We got to see his other side as well since we always only see his romantic acting side. This drama also has a good message to always check upon your friends as some might be struggling quietly ?? And to always ask for help when needed.
