Romantic doctor
Some characters do have romance but it's not the main focus the name is really misleading xD (MINOR SPOILER: main guy is an older loner genius doctor saving people and he's the one called romantic doctor )
Our blues
This one also has love but it's viewed as part of life not in the way kdrama romance works. It's a very unique one just depicting people being human
Strangers from hell
Scary psycho murder shit. It is very scary so be warned.

what's yall fav kdrama that's not focused on romance? i just finished two kdrama series from my list, i need more to watch
