darkeyedwolf's post on her fave drama kisses made me want to do my own list but it also reminded me of
Devil Beside You. I am not a huge fan of the drama (too fluffy for me) but back then it was the first drama I've seen with so much kissing. Thankfully some kindly youtubber compiled them all.
Did I mention they are stepsiblings? They must be the CLOSEST stepsiblings ever!
