She would only smile secretly at me. Shirakusa is an active female high school writer who won the Akutami Prize! And she's a beautiful girl! I know she and I - ordinary high school student Marusue Haru - are not a good match! However, I think she has feelings for me, probably, no, definitely! I thought so... but then I found out that she has a boyfriend? ! Facing my depression, my childhood sweetheart Shida Kuroha, who is petite, cute, caring... and outspoken about her love for me, said to me... "Revenge." The resentment of first love is deeper than the sea... but it's never dark! It's never complicated! The revenge of first love begins!
