* Male lead pretends to be gay in relation to a job
* Female lead falls in love with someone whom she thinks is gay
* Someone the male lead woks with is gay and falls in love with the male lead

** PLEASE NOTE THIS CONTAINS A HUGE SPOILER (or two) **

- Both contain leads that struggle with ethics/following the law
- In both dramas, a character attempts to split up the couple
- Both involve orphans
- The leads know each other from childhood (but have forgotten for most parts)
- They both have a very similar ending

Both dramas are about people facing hardship in the fashion industry and include several possible love interests

Both dramas involve the FL living another person's life (in Mask while being a doppelganger and in 49 Days by possessing a body). I feel like the melodrama aspects of them are somewhat similar as well.

**MINOR SPOILER ALERT?** (it's revealed from the beginning or very first episodes)



Both dramas contain a man who is a cyborg (part robot)

Both dramas include supernatural elements and revolve around a private investigator and his assistant

Both dramas have a time travel aspect and I feel like the reason as to why they time travel are very similar. *SPOILER ALERT* I wouldn't necessarily say this is a spoiler but, you know, just to be sure. I feel like the reason the characters in both dramas are experiencing time traveling is because it will help them realize what they value most in life and pursue it.
Both dramas are also focused on job occupations (though one is about doctors and the other is about police officers).

They have a similar kind of humor (though The Fiery Priest is more often and more exaggerated in use). Kim Nam Gil is the lead in both the dramas too but that's practically the only similarities.

Both dramas revolve around the law where the leads work as a lawyer or a prosecutor.
The female leads in both dramas are not the typical people to find in the job as they are very fashion forward (aaaaand both of them love the color pink). They both have a great memory but are somewhat airheads which makes their work hard in the beginning. The male leads in both dramas help the female leads out and they, of course, fall in love with each other.
