Some good drama comedy romantic K dramas?

Hi! I was looking for a good kdrama. The last one I have finished to watch yesterday was Heartstrings. I liked it, ever if I liked thêm bạn are beautiful!

Some kdrama of this kind? Not too action and not so much serious stuff. I prefer funny dramas... At least the only one I would say was sad is 49 days! (I liked it, btw, it was very deep...) And if the main character are not student is would be perfect!

I have already watched:

- Boys over hoa
- Coffee prince (I really enjoyed this one!)
- bạn are beautiful
- Lie to me
- Secret Garden
- 49 days
- hoa Boy tiếp theo door
- Heartstrings
- Romance Town


So any suggestions?
Thanks!!!
