Story had much more potential, ending could've been better, characters felt under-developed.

Pros:
1. The drama does have a good story and acting with frequent plot twists that keep you engaged.

2. There are no k-drama cliches.

Cons:
1. The story felt like it was hurriedly done and could've shown more about the relationship between leads.

2. I felt that it could've used less technical jargons, which makes some parts of the story boring.

Good watch nonetheless.
