Looking for Kdrama Recomms

Im trying to venture out of my bubble of cdrama/tdramas so I was wondering what are some good kdrama recommendations?
I enjoy rom-coms only when it does not involve a love triangle...aka the main casts aren't wishy-washy about who they like throughout the show (like Boss&Me/My Sunshine/ Mars). 
That said, I also enjoy good action based plot which using romance as a sideline/tag along. Thanks!

Healer (action romance)
City Hunter (action romance)
Secret Garden (fantasy romance though there's a lot of push-pull)
Descendants of the Sun (realistic yet still a fantasy romance, again push-pull)
Reply 1997 (high school slice of life, romance, comedy)
Kill Me, Heal Me (psychological, romance mystery)
Pinocchio (mystery romance)
I Can Hear Your Voice (mystery romance)
Oh My Venus (realistic romance)
Innocent Man (revenge romance)

Sungkyunkwan Scandal is a good intro to historical dramas if you want to try them either that or a time travel drama like Queen In Hyun's Man or Rooftop Prince

there are also Korean versions of some of the dramas you[ve seen like To the Beautiful You (Hana Kimi), Playful Kiss (It Started With a Kiss), and Boys Over Flowers (Meteor Garden, though I think the Japanese version is best)

I have listed ones that hasn't been mentioned yet :) they're not just rom-coms but also action/mystery 

It's Okay That's Love 
Coffee Prince - Gender bender theme  
Please Come Back, Mister - Action/mystery too 
The Master's Sun - Mystery 
She Was Pretty 
You Who Came From The Stars - Scifi

Below are those dramas that were very memorable for me:
Hotel King

Marriage Not Dating
Secret
Wife's credentials
Gentleman's Dignity
Lie To Me
That Winter, The Wind Blows
Scent of a Woman
Protect the Boss
