Jin was your average, everyday school teacher. He taught high school students. He got along with his students. Jin taught a history class. But one day when Jin was walking to his car somewhere around 9 at night, something hit him over the head. Next thing he knew was he was waking up in what felt like a cage but he couldn't tell because he was tied and wearing a blindfold. The major problem was, he only remembered his name but his past wouldn't come to him. All he could recall was that he was 21 and his name was Kim SeokJin.
