I don’t know how to rate this drama, if I remove about 75 episodes, I could give it a 9 or 10.
I had to skip a lot of random episodes to enjoy this.

Yoona did a good job carrying the bulk of this drama considering it was her first go as a lead and she was 18 at the time.

The ML had an weird facial expression( he has the same expression in “Tale of Two Sisters”), it takes you out of the scenes he is playing.

The other ML’s anger issues became tiresome after episode 2.

The writing was amateurish/lazy at times, using the “lack of clear communication” plot device to stretch out the story and create tension, drama and comedy. Introducing characters to fill time.

If you focus on the Yoona episodes it’s an enjoyable watch.
