The first eight episodes is like romantic comedy, the main lead is aloof and very silly
The last 8 episodes is more serious, zero comedy, thriller, suspense, mystery, anything can happen
There is also plenty of twists, one big twist near the end, my best advice is don't try to predict whats going to happen next for you to enjoy this
The actors acted out everything on point, I feel they all did an excellent job, especially the lead male actor, he was on point
The cast is likable, An, Jae In, An's Brother Seong Mo
Music is just right, not like omg so good put on repeat but sounds good
The pace is not bad, slow at times but it wasn't boring, story keeps going

This drama worth watching, dont try to predict the plot and it will be a fun ride, i promise you that much, dont try to predict it !
