The princess of the class is my doggie.

I, Kurumi Nabana, and my classmate Seira Sorahashi aren't friends. In fact, we hardly ever talk in the classroom. I am a plain, ordinary girl, and she is widely considered to be the cutest girl in school, so our social circles do not intersect. Until one day, when Seira summoned me with a note to meet after school.

"Kurumi,” she said, ”Would you like to be my master?"

My daily life is dramatically changed because of this ridiculous “request." I tried to think of excuses, but I wouldn't want anyone else to hurt Sorahashi-san. So I said, “I'll do it....... I'll put it on."

From today, I will be her master. Put a collar on her, train her, and take her for a walk behind closed doors.

What in the world are we doing?
