Since I've reincarnated as a heroine, it's okay to have a deep bond with my rival!? - My Youth Game (Tentative Title)

I was hit by a truck and my life ended, but a cat that saved me became a goddess and guided me to another world. Wait, isn't this the world of that niche otome game I bought after being fooled by the cover!? And I'm supposed to be the heroine!? A love and battle academy life begins with me (male in my previous life) who has been reincarnated into another world and become the heroine!! As you can probably tell from the character count, this starts abruptly and ends quickly. It's just a concept I wanted to try writing. The BL is only hinted at subtly. Half of it might come across as GL.
