Onii-chan, how much money did you bring?

Ruri brought 5,000 yen.

If you're gonna be mean, I'll tell mom.

1 billion yen.

I want to buy clothes and stuff. Onii-chan, you buy me ice cream.

Get off your high horse.

Scum.

You like buying me ice cream, don't you?

And if I can't afford the clothes, buy those too.

And I wanna go to the park and stuff too.

...I only went out to buy a book in the first place and you invited yourself along to get in the way, so you don't get any human rights right now.

Don't get cocky. Just you wait till we get home.
