Actually, I was a perfect match for my sister, and she was my favorite! My sister who lives in the countryside came to visit me in Tokyo! However, I always saw her as a woman, and I thought that I couldn't do that, so I ran away and started living alone. But when I met her again after a long time, she had grown into an adult body.
