Akane Minagawa is a music teacher at a high school. At school, she displays a docile, gentle, kind, nurturing and airheaded personality, which makes her instantly popular. However, outside school, she's the complete opposite. She goes out with many men and enjoys playing with them, although she grows bored of them quite fast. Hence, she spends very little time with them after she lures them into sleeping with her.  She has never been in love and doubts she ever will.
