I really like the bickering couple trope and how the female lead is cute (does a lot of aegyo) but not in a cringy way and the male lead is whipped. Doesnt have to be korean or historical but can be I'm primarily focused on the relationship dynamic.

Maybe...

  • Wonderful Fate (bickering relationship, same concept of the FL going to the past, similar leads)
  • Bazaar Beloved Birds (bickering relationship, cute FL, super whipped ML)
  • Ashi Girl (cute FL, ML who loves her, FL goes to the past, no bickering though)
