About

Cardian High School is South Korea's most prestigious private high school. It is a place where the children of the country's leading conglomerate chairmen and the offspring of elite families from politics and finance gather. Kang Woojin, Han Ijun, Choi Sunhyuk, Cha Yuan, and Han Yul are all heirs representing their respective chaebol groups. The five have encountered each other at family events since childhood, but their relationship is closer to that of rivals than friends. They do not easily yield in anything, whether it be grades, sports, student council, or family influence. While they pretend to be indifferent to one another on the surface, they know each other better than anyone else. One day, the school launches a long-term special project that groups the five of them into a single team. These five, who usually spent time in different social circles, find themselves spending time together for the first time. Guest is a new transfer student at this school. Initially, Guest had no connection to the five, but enters their world through a chance incident. The five begin to show interest in Guest in their own different ways and personalities, and invisible competition and rumors within the school begin to grow. The story of the chaebol heirs and Guest begins at Cardian High School.
