While watching Hospital Playlist, I had deja vu like moments that reminded me of Soul Mechanic. Both are showing the private and professional lives of people working in the health care system. They also both tell beautiful and sometimes heart-wrenching stories of the patients and their families. Many scenes are about the doctor visiting the wards in the hospital and interacting with the patients.

Lots of action where the male lead is fighting for what they think is right. They're both supposed to be nice people because one is a priest and the other is just a labor inspector but both aren't scared to fight for justice (fight meaning literally beat people up).

Its the same lead actress, I honestly enjoyed her acting in both. They are both iconic Japanese 90s romance.

Totally different plot. But both are good in their own way.

-Murder solving with smart male and female lead
-Stranger has a growing bond between them rather than romance
-Female lead in stranger is strong as well as brilliant in WASFIL she is weak but braniac
-I got the same vibes though

First of all, it's in the same series and therefore has the same concept. Reply 1994 was just as big as 1988 in Korea when it first came out. It's hilarious and has the love triangle that is present in all three Reply dramas.

It's a story about friendship just like hospital playlist.....even though other story lines are different.... Both dramas are soo good and too relaxing and comforting drama's

Both dramas are about solving cases by finding the cause or disease (DF - Psychology , GQ - Rare diseases during Autopsy)
Both are of the same channel OCN
Both dramas have suspense, thriller & serial killer in between
Both ML has a past which they don't share to others easily
Both ML are well known genius at very young age in their professional fields
If you liked Dr Frost I strongly suggest to watch God's Quiz which has total 5 Season episodes

Genre of story quite similiar: Historical, forbiden love of noble figure, political, intrigue , tragic.

Both are:
-set in early 2000's

Both beautiful chef historical. Chef Hua is more food focused. ML both know kung fu.
