Tsundere Idol: My Personal M-Pet

Tsundere Idol is the story of Kota, a mild-mannered student in Japan and idol sensation Rui Kurumizaka.

After Kota steps up to claim ownership of an S&M magazine that spilled out onto the floor during a stereotypical romantic encounter between him and his beloved idol, Rui-chan, she confesses to him that she'd always had her eyes on him and she wants HIM to be her master!
