Twists and turns around every corner and an ending that leaves you with your jaw on the floor. A creepy hostel where everyone in it is harboring some dark secret or evil side of themselves, but inside there are no rules. Yoon Jung-Woo moves in and slowly begins his decent into madness.

--Spoilers Below --

Yoon Jung Woo when he's first introduced is a handsome, smart guy who is pursuing a job in tech. His girlfriend lives in a different city and is working for a large company. Jung Woo finds everyone in the hostel creepy and somewhat strange, but cannot find another place cheap enough, so he stays there. He slowly begins making friends with some of his neighbors, particularly a handsome dentist: Seo Moon Jo. As the months go by, Jung Woo finds his life dreary and finds everyone around him annoying and beneath him. His coworker speaks down on him, but is secretly a pervert. His boss who is supposed to be his friend... is trying to steal his girlfriend behind his back. He cuts every one off and begins spending more time with Moon Jo. Their relationship, although odd, was one of my favorites in the show. As more and more time progresses and the longer Jung Woo stays in the hostel, the more his mind goes crazy. It's hard to tell what's real and not real and in the end, he's the one who pays the price fully.

Seo Moon Jo is a serial killer who has been hiding in hostels with other killers moving around for years. He works as a dentist for his ordinary life and comes home to the hostel and is cannibal by night. He found solace in Eom Bok Soon and they begin running the hostel together as a cover for killing and eating people. They kill tourists and random people who come through, never being enough evidence for the hostel to be considered or they leave before the cops can come for them. He is more controlled with his killing and methodical and also wants to find a prodigy to pass on his talents and live on in them. Moon Jo slowly brainwashes Jung Woo and falls in love with him, making him do whatever he wants, and Jung Woo not even knowing. He knows what Jung Woo is capable of and brings it out of him. Towards the end as the cops zero in, he gets Jung Woo to kill him and completing his wish of living on inside of Jung Woo's mind.
I loved his character and the way Lee Dong Wook played him. Such a dark and evil character, but has such a charisma that even pulls you in as a viewer.

-- End of Spoilers --

I didn't care for the cop side of the story at all because the more interesting side of the story was in the hostel, in my opinion. I skipped through most of it and stuck with watching the main plotline. Other than that, I would say it's not one that you would be able to re-watch since the main mystery and thrill is gone, but it's still a great, easy, short watch.
