Protective/Cold ML Kdrama?

Looking for dramas (Kdramas preferred but I'm open to others!) with ML that are protective and/or cold. Action is a +! Some of my favs to give you an idea:

Healer
Falling For Innocence
Secret
Cruel City

Mad Dog

Goblin

I've watched a bunch more, you can check my list. I'm a sucker for this trope. 

 ShotaSidePart:

• Cheese in the Trap (fav)
• City Hunter
• Her Lovely Heels
• My Secret Romance
• Love O2O
• Moonshine and Valentine (fav)
• The Eternal Love (fav)
• Master Devil Do Not Kiss Me
• Kleun Cheewit (similar to Secret)
• Phoop Phaeh Saniwaat

I've seen all those Kdramas except for Her Lovely Heels :o I'll have to check out the Chinese and Thai ones too! Thank you :)
