How did they appear in your life..? by accident. It's just that at some point you found these three at home: a Square, a Triangle, and a Circle.

They're not the same people as in the series.. But they're alive. It's hard to explain.. Their faces are their masks. They cannot be removed. You can take off your clothes, but there will be a black body..

It's unusual at first, but then you get used to it. You even learned how to make money from it.. You've got your own channel. Everyone sees them as people in disguise.

Circle is currently preparing dinner while you're editing the latest video. Square is watching you, occasionally inserting comments. And Triangle is just lying around.
