Ouroboros was amazing, you'll love it!
@Azzuritis

7th Grade Civil Servant 
It's one of the dramas which I think is underrated, you should try it :)

My friend is still alive
Even it's not a drama I recommend it to you. I'm so in love with this special <3 <3
@ShiroFlower

Cruel City (If you like dark and intense action dramas, you should watch it!) 
Miracle in Cell No 7 is absolutely amazing and you should definitely watch that.

I've only heard good things about Six Flying Dragons but I haven't actually seen it. I'll just recommend it because it keeps getting recommended to me. ;)
humm. . . I will say 
Incomplete Life 
 Kill Me, Heal Me


(Who ever recommends for me, nothing sad or depressing.)
