Both very good mystery dramas with great acting. Suspense is also good. The mystery is entertaining and they both leave you off of your seat thinking about what's going to happen in the next episode. Both also have strong female leads!

Both medical dramas. Both involves doctors who'd rather save lives rather than being a doctor just for the money. Similar plot.

Both have mentally strong and smart female leads. I think Princess Wei Young has better chemistry between the two main leads.

I feel like these two dramas are very similar in a way. It's basically about the past but the drama is in the present form. Both are interesting and the bromance is cute! xD

They both involve crime and both dramas will make you not want to move away from your seat! :) Both are beautifully made dramas. Also, they don't have much romance in them.

They both keep you at the edge of your seats and won't let you fall just yet. Also, you're always feeling apprehensive about what is going to happen next!

Both dramas are pretty intense and each ep has a cliff hanger at the end of each episode. They also also both very well written dramas with amazing actors.

They both are about revenge and the main leads take the blame for what their lover's wrong doings because they can't picture their lover in jail.
