Hitori-chan, since we're lovers now, I was kinda hoping we could drop the keigo.

Oh, uh, I wasn't using it because I didn't think we were close enough or anything...

It's just that I've never used anything besides keigo to talk to people outside my family before, so I don't really know how I should speak...

Well then I just need to become part of your family then!

Wha-

If we were family members, maybe I'd be your big sister!

Oh! That... Maybe so!

That's kinda disappointing...

So... so that's what she meant... I almost thought that was a proposal...

I can't believe I got so carried away I almost proposed to her... she bought that excuse, right...?
