So I've come to realize that noona romances may be one of my favorite kdrama trope/genres. I've seen Witch's Romance, I Hear Your Voice, I Need Romance 3, King of High School Savvy, and Secret Love Affair...

Any other suggestions? I like when the fact that she's a noona is part of the central storyline/~~conflict~~

Flower Boy Ramen Shop 
The Lover (one of the couples) 
Like for Likes (movie, one of the couples)

Here's a list of noona romance dramas and movies http://mydramalist.com/list/X3bXzG1l created by Geanina
