My childhood friend Shida Kuroha seems to have feelings for me. She lives next door, and is small and cute. With an outgoing character, she's the caring Onee-san type, this being one of her greatest strengths.
...But, I already have my first love, the beautiful idol of our school, and the award-winning author, Kachi Shirokusa!

—If it's that tough for you, then how about we get revenge? The best revenge ever, that is~
