storyline : basically sooah starts working as a trainee teacher and she finds out about one certain student (young seok) that hasnt come to school in quite some time. she decides to go to his house (very creepy) and persuade him to come back to school. he ends up coming back but he's very odd and says weird things to her. low and behold he has a big secret which she shouldn't have messed with.

acting : when i say the acting was AMAZING i really do mean it was AMAZING. by amazing i mean yoon suk (young seok). his acting here was really good and he's perfect for this kind of role. youngseok was by far my favourite character here, solely because of his creepy aura and top notch acting. i've been watching a few of his dramas and honestly this drama really showcased his talent. i hope he does more roles like this because they really suit him and he can really pull it off.

music : i didnt pay much attention to the music so i cant really rate it.

rewatch value : i could honestly watch this everyday. not to exaggerate but this drama really creeps me out and is my favourite out of the whole series.
