I became a girl, so I'm going to confess to my best friend that I love them.

I'm Kōsmiragim Haruka, and I'm in love. The person I love is my best friend... Shinonome Kazuto. However, no matter how much I like Kazuto, he will never see me, a boy, as a romantic interest. That's why I have to lock away these feelings deep in my heart. Even when I'm talking with Kazuto and Aoi, or studying with just Kazuto and me alone in a room. But no matter how hard I try not to think about it, I find my eyes following Kazuto, and even during class, I get distracted by him and end up looking his way. My heart races just from making eye contact with Kazuto. Ah, if only I could become a girl, then I could tell him I like him. Carrying these worries with me, I see Kazuto every day. This is a story about what happens when I, who has wished to become female, actually becomes a girl. It's a tale depicting the final year of middle school for me and Kazuto, and our other best friend, Morita Aoi.
