Ryuhei Ohno spent much of his middle school career pining for one of his teachers. Not only are teacher and student relationships taboo, but Ryuhei was head over heels in love with one of his male teachers! With his years of unrequited love behind him, Ryuhei is looking forward to turning over a new leaf in high school. And to make things even more promising, Ryuhei has entered a high school where 90% of the student population is rumored to gay. However, a couple of the students in Ryuhei’s class haven’t heard the rumors surrounding the school. Kunihisa Imaizumi is cute, adorable and homo-phobic. Unable to deal with the increasingly bold advances of his classmates, he appoints Ryuhei as his “knight in shining armor” to keep his suitors at bay. Ryuhei is more than happy to protect Kunihisa’s innocence at first, but even Ryuhei finds himself falling for Kunihisa. Who is going to protect our “poor maiden” from his knight?!
