Any tear jerker/ sad C-Drama to recommend? K drama is fine as well

My top favourites were

1. Ashes of love
2. Eternal love / Goblin
( I found the storyline of Eternal Love and Goblin much better than Ashes of love but Ashes of love was much more painful. )
3. Moon Lovers Scarlet Heart Ryeo
4. Goodbye my princess
5. Someday or one Day
6. Bloody Romance
7. Go Go Squid

Basically, I love it when someone dies/is in a lot of pain/loses something extremely valuable after sacrificing a lot, etc. Camaraderie elements involving achievements and pain are great too, like GoGoSquid.  

Just a note, I hate superficial stuff like Love O2O.

I hope I can get some recommendations... I've been dropping too many shows halfway... Thank you!!!

Since I pretty much only watch costume dramas, here are some that made my tears flow:

K-dramas:

My Country New Age

Chuno

Warrier Baek Dong Soo

 Mr Sunshine

Apart from Mr Sunshine none of them has romance as a main theme though ( and questionably Mr Sunshine  uses romance more as a mataphor of sorts)

C-Dramas:

The Untamed

I suppose "The Wolf" could be considered sad and tragic enough but somehow it didn't make me cry ( but romances  not often do)

I'm also desperately looking for some new sad dramas  like NiF,  Bloody Romance or Goodbye my Princess to watch !
