any drama where broken or separated lovers patch up?

eg: emergency couple 

  • Cunning single lady
  • Motokare mania
  • Discovery of romance

These are more like high school sweethearts that find each other when they are older but check out: 

1. Refresh man (Taiwanese)

2. Reply 1997 (Korean) 

Additionally ones not mentioned yet, but nearest with emergency couple of second chance romance ( Divorced couples), though not so great ones are:

  • My Secret Hotel
  • Paradise Ranch - not so recommended

There are others with ex-childhood/highshcool sweethearts (Wild chives and soy bean soup), or others with amnesia plots, and some with amnesia plot. But decided to list only the Divorced couple instances.

Live (secondary couple)
