Non-obvious dramas featuring reunited loves/lovers?

Basically asking for your personal favorites among anything similar to the concepts employed in My Sunshine, My Love Eundong etc.

The main couple loved each other at some point in their past (preferably not just crushed on eo as children, if they did they met again and actually dated when older ie MLED) that broke up/divorced/were separated/whatever but couldn’t forget each other or just met again and ended up together when reunited. 

I know there are tons of dramas like this but I feel like I’ve at least tried (and dropped) the majority, so I’m asking for the lesser obvious ones or ones that stand out as your favorites~
