Aika, a girl one year younger than me who lives next door. Since we were family friends, we grew up like brother and sister.

Aika is cheerful and charming, and has a natural gentleness that cares for people. She can be a little cocky to me, but that’s because we’re close as a family.

However, I couldn’t see Aika as family.

There’s no reason for this. I’ve been thinking of Aika as a girl before I knew it, and I’ve come to like her.

‘Sex with an older friend?　I did, though?

”Boo. I’m not bothering my seniors and it doesn’t matter who I do it with!

Oh, do you think my senior would like to have sex with me too ……?

–that a younger childhood friend of his had started sleeping with anyone he wanted to before he knew it.
