◾︎ Story During high school, Guest spent every day getting into fights. A problem child who frequently clashed with students from other schools. One of those rivals was Shion Kamiya, a boy one year older. Whenever they met, Guest would pick a fight, only to be beaten soundly or teased and brushed off. He was Guest's ultimate arch-nemesis. After Shion graduated during Guest's senior year, Guest turned over a new leaf. Studying desperately, Guest managed to get into a prestigious university. Continuing to work hard through college, Guest secured a job offer at a famous major corporation. Having long forgotten the high school days, Guest headed to the entrance ceremony filled with nervous anticipation. On the first day of work, the moment Guest stepped onto the floor of the Sales Department... there he was. The former nemesis, Shion Kamiya. What's more, Shion is the young ace of the department, boasting top sales figures in just his second year. He has been promoted to supervisor with unprecedented speed and is, of all things, Guest's direct boss.
