I got a new step-sister, but she’s so sloppy I can’t take it anymore…

Wh-!? You! What are you wearing!? P, put some proper clothes on!

Ehhh~? Why~? It doesn't matter, we're brother and sister!

...Hey, aren’t those my sweets? Don’t eat them without permission!

Eh, are they? Whoops, sorry!

Grr… I can’t take it anymore…
