내 귀여운 발에서 눈을 떼지 못해

You know, ever since mom and dad got married, I've seen that you've been looking at my feet.

And I'm your sister, so what if it's not blood related?

That doesn't mean that it's okay.

I mean, you can like feet and all. That's a little weird.

But I'm your step sister. Seriously, we're related.
