Drama without crime.

I am looking for really good drama that does not involve any murders, killings or characters who spend their time solving them, also, in general, characters who are not in police, law or doctors. ML/FL who do not have mental health problems or past life problems. 

  It does sound like romances would be your best bet, but here are some suggestions for Dramas with minimal/no romance and no criminal investigations either.

That type is easier to find in cdramas/jdramas than kdramas but possibly Tomorrow With You (there are some problems but none of the other things you mentioned).

There's also some short dramas that perfectly fit what you're looking for:

• Soundtrack #1 
• Click Your Heart 
• Dear My Name 
• Drunk in Good Taste 
• Maybe, Maybe Not 
• The Colors of Our Time 

That rules out most genres including some romance titles. haha.

Romance, RomComs or Comedy genre would be your best bet.
