GUYS ITS SIMILAR TO SANGWOO AND A YOONBUM STORYY

No it's not.
Just because KS it's the only horror/thriller you know doesn't make every other thriller be similar to it. One is a stalker who's in love with a psycho and breaks to his house, ends up kidnapped and participates in his crimes due to love and stockholm syndrome. The other is an renomed Author who's a serial killer and likes playing twisted games and manipulating people.
He didn’t deserve that :( cliffhangers
