A Good Wife (TW) - affair drama but one of the realistic ones I've see
Wake up (TW | S1 and S2) - medical drama, totally a different type of breath and plot than your other medical drama. And their plotline definitely feels more realistic than some of the dramas outh there.
Alone in Love (KR) - very old, and I could not get through this when I watched it the first time years ago. I guess I was too young to appreciate it
