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).

The two drama had an almost similar plot that is a doctor time-slipping between two different time periods. But in JIN's case, it was a modern doctor who ended up time-slipping towards the past. To be fair, I would've recc Dr. Jin that was a Korean adaptation of JIN for the sake of sticking to the same Korean setting but I might as well recc the original instead.
