The Binding Bride's Garden

In Akane's eyes, Riri was a princess, so Akane decided to become a prince - a handsome idol that all the girls admire. The only problem is that Riri is already engaged to Gaku, a teacher at school. In order to keep him away from her, Akane agrees to go out with him, but she finds herself struggling to maintain her princely image as he starts to coax out her body's natural urges.
