It's more of an open ending, so you can make up your own ending, how you think it ends.I wanna believe it's either…
He tried to help Yu Ri (I think) because she got injured. They got to a car outside the building but died. Yu Ri said something along the lines of "I killed a person." because one of the gang members tried to kill her and she saved herself and Yi Kyung. Yi Kyung couldn't help a lot because she had a surgery done by Eun Hyuk a few episodes earlier. Then Sang Wook told her to not think about it and I think they held hands as they passed away.
It's more of an open ending, so you can make up your own ending, how you think it ends. I wanna believe it's either that Sang Wook survived after all and saved Hyun Soo and then they tried to save others or something like that OR the thing that came from Eui Myeong went inside Sang Wook and then helped out Hyun Soo since he said he's gonna go with him.
Agree and REPEAT:DON'T WATCH IT ALONE AT NIGHT.(I did the same mistake and I am unable to sleep for an hour now.)
It's not even that scary? I watched most of the episodes at night and it wasn't as scary as it seemed. Some scenes were just more suspenseful than others but that's about it.
I absolutely love his character in Strangers From Hell. I just finished it and wow. Fell in love with him more and more in each episode even though he was the bad guy.
to name a few:
make me shudder
pee mak
secrets in the hot spring
