I've known my old male friend since we were kids. Naturally, I always hung out with his younger sister, Miyu. Then I entered university and lived alone. I was enjoying my university life and doing well academically, when Miyu enrolled in the same university as me. Miyu... did you like me? I'm ugly. Even before I confessed that I liked Miyu, she came to my house to hang out... and then, a few years later, we finally crossed the line.
