A new principal takes over a school facing financial difficulties. However, he couldn't care less about turning the school's finances around. His true goal is to establish a new business model by turning female students into exclusive escorts for a select group of wealthy clients through a secret JK brokerage club. The primary targets are Rumi Kanda, a quiet, beautiful girl who despises men, and Sayaka Otonashi, the school's beloved idol. The two are close friends, and they gradually become entangled in the principal's scheme. As the student council president, Sayaka is completely under his control, and together, they transform into the club's most sought-after commodities. As their descent begins, the dark undercurrents lurking beneath the school's everyday life start to surface.
