Yuzuru Hagino is an ordinary high‑school student attending Houjou Academy. The school offers a special program called the Kuge course, reserved for students whose names contain a flower. Within this course, a “Honey system” pairs each privileged student with a regular student as their “honey.” The master pays the honey’s tuition and has authority over the honey, who must obey all commands. Yuzuru becomes involved with Renge Kai, one of the Kuge students, and the situation could turn into a serious mistake for him.
