The Plot itself is very good and well thought off. The Acting was really good it had successfully conveyed the feelings and the message that is being shown. Watching this drama at the start gave me a fluffy feeling. The comedy and drama at the start is a very good balance. It made me laugh while seeing the main's chemistry.

As the drama transitions into something that touches your heart ,even you still don't know the truth.
The fact that it fooled many viewers about the plot and gave us a shocker!
One of the best Kdrama I have watched Plot wise.
