The most shocking deaths in Korean dramas?

This has a lot of spoilers.

I was pretty chocked that in I Hear Your Voice the female lead mom died... for me the drama didnt seem to have a dark aura, so, even if it was about criminal cases, I didnt assume she was going to be assassinated,

In The Guardians the male lead is presumed to be dead at the end too... but who falls off a building really high and stays alive? Anyway, I was speechless for a minute when I watched.

Also, Queen for Seven Days, Seo Noh's death was too painfull too watch. 

Hong Gil Dong. It's a comedy a lot of the way, they keep escaping death and the authorities but man that ending.

I saw that coming in 'what happened in Bali'

I would to add:

49 days (I'm still crying #PTSD4life)

Empress ki (I don't know what to say.......they didn't want to see her win ????murdered mother, long lost father tortured death and posisoned son-never got to tell him who she was AND the love of her life!).

Healer (that death plot is the only reason why I will never watch it again).

King 2 heart- unnecessary death of the hot???? bodyguard 

Rooftop Princess- 'real' Princess (I'm still angry with that ending).

What happens to my family- the father Dear drama writers, 'why tho?????????'

Six flying dragons- the raped victim (stabbed herself to save everyone)

Chicago Typewriter- all their past selves deaths (i found it beautiful and emotional even though it was the main plot and made the their present storylines more interesting. But it was their level of acting in their death scenes that made I want them to survive but at the same time being beautiful watching die for the what they believe in/what they did/the one they loved.

Scarlet heart ryeo... had so many sad bits. Especially the end. Jesus, I had to recover emotionally for a week after watching it.
