I really love dramas where the couple is together happily and the central conflict isn't really their relationship, for example, Strong Girl Do Bong Soon and Shopping King Louis. I don't mind if there is a bit of jealously like in SGDBS but I don't like the whole misunderstanding trope (unless it's more of the super funny light hearted kind).
So I'm looking for some recommendations of romance dramas like those two, not in terms of their plot but really the state of the couple's relationship throughout yet still has a really engaging plot.
