both have:
- estranged spouse realizing they are actually still in love with each other and are the only ones that got each other back
- these realizations are triggered by death/near death event.
- female lead has higher status than male lead
- the female leads have another courter and the male leads are jealous over them

- both take place during a war.
- similar mischievous female lead who later transformed after the experience of war
- similar 'huh, did i actually love him/her?' romance trope

honestly my dearest will broke you and you'll need a remedy. romance-wise battle of changsha will help you recover (emphasize in romance part because everything else will probably broke you more than my dearest)

both shows produced by same PD, same company, with the same theme. the content are different but both shows girls having fun in south korean countryside.
