「Miyo, shall we sleep together again today?」

「U-uh, yeah...」

And just like that, my older sister—Iwamoto Haruka—invites me to bed.

To an outsider, we might seem like we have a good sisterly relationship. ...No, it's not like it's bad, actually; in fact, it's rather good... The problem is that it's *too* good.

The feelings my sister directs towards me aren't sisterly affection, but the love one feels for a romantic partner.

I know it's all my fault. But I'm not homosexual, and more importantly, I don't have such feelings for my sister... for my family. Of course I love my sister, but that's as family, as sisters.

Really, if only I hadn't done *that* back then...
