Based on a true story from Bongcheondong, Gwanak district, Seoul. Jinki and his four dongsaengs were walking home after a tiring study-hall that night. Minho had to buy something for a project, and the other three; Jonghyun, Key and Taemin, decided to tag along. Since the route from the store to their dorm was closer through Bongcheondong, they decided to walk through.
