This will surprise you, frighten you and in the end, sadden you. One of the best thrillers, from acting to storytelling, each and everything was crafted so beautifully that you'll be amaze at the skills of the director. Big shot out to the guy, Jang Hang Jun, man made for thrillers. And music 🎶, treat to the ears, after a long time I heard something that set the mood for me.
Recommend to everyone.
