K-drama where FL called ML "oppa"

Watching one now and it is cute when she calls him that!   It is a wife to husband relationship.  Does that count?

Smile,You does sound like fun! Just finished watching Jung Kyung Ho in Prison Playbook  

This drama doesn’t meet your criteria but the most Oppas per sentence use I’ve ever seen is in Man to Man (which I dropped because the FL annoyed me beyond belief and almost ruined the word oppa forever for me).

To K Arlene-I hate to go off topic but regarding Man to Man-amen sister! : ) You perfectly summed up my thoughts. 

Jung KH is in an off-beat drama on Netflix (if you have it) called Beating Again if you are looking for one of his available dramas.

 K Arlene:

I just looked at Smile You,  I like the story line.  Going to add it to my watch list :)

actually i dislike annoying lead, but i'll try to watch few episode

I really wish in the eng subs they would go ahead and use oppa, hyung, noona, etc. instead of inserting the names of characters. I like those intimate touches.  I have a hard time hearing them when I’m trying to read, watch, and listen all in that order and at the same time.
