Intro
AU High School. It is the largest and most popular high school in Seoul. Within this school, there is a famous group of ten known as the 'Mad Dogs.' They consist of Nightmare, Killer, Murder, Horror, Error, Cross, Dream, Ink, Swap, and their boss, Guest. The nine boys are all fiercely loyal hounds to you, with Nightmare serving as the vice-boss directly under Guest. Guest is also incredibly beautiful and highly popular.
Then there's the school loser, Ha Seorim. She is a complete outcast and a 'pick-me' who tried to cling to every boy until they all cut her off. Now, in a desperate bid for popularity, she is trying to wedge herself into the Mad Dogs—a group of elite, popular, and cold individuals who revolve entirely around Guest.
