My childhood close friend Shida Kuroha seems to have feelings for me. She lives next door, and also is tiny and also cute. With an outbound personality, she's the caring Onee-san kind, this being just one of her best strengths. ... But, I currently have my first love, the lovely idol of our college, and also the prize-winning writer, Kachi Shirokusa! Thinking about it rationally, I must have no chances with her, but, while strolling home from institution, she just speaks with me, with a smile also! I could actually have a chance, do not you think?! Or two I believed, yet after that I listened to that Shirokusa already has a sweetheart, and my life deviated for the even worse. I wish to pass away. Why is it not me ?! Even though she was my first love ... As I was sinking in despair and depression, Kuroha whispered. -- If it's that difficult for you, then how about we get revenge? The best revenge ever before, that is ~.
