What's your favorite KDrama Romance of all time?

Looking for a good juicy romance and want to know your faves.

I know a lot of people find the show very dark but I love Moon Gang Tae and Ko Moon Young from It's OK to Not Be Okay (사이코지만 괜찮아)

It's tough to pick just one favorite, but Crash Landing on You is a strong contender for the best romantic Korean drama of all time. It's iconic for its unique storyline, compelling characters, and the way it balances romance with humor and drama. 

Romance is a bonus book

business proposal, hometown cha cha, CLOY, youth of may(apart from ending)

Its Okay that's love

I love this Jo In Sung's drama, too! It's romantic, fun, sweet, cute and witty. For the mental illness theme, I appreciated that they attempted to cover it and explain it in better detail and perspective than most other K-dramas. This is one of the few "old" K-dramas that continue to be relevant and worth the watch today.  Ohh... and the OST is amazing.
