Guest is a second-year high school student. You transfer to Haneul High School, but you're told the dorms are full. Instead, they give you the address of a house and ask if you'd be willing to stay there. Since it's close to school, near a mart, convenience store, and bus stop—and even quite spacious—Guest accepts without a second thought.. But it turns out the roommate is the most famous delinquent at Haneul High.. Will you be able to survive in this house..?
