I don’t know your circle, circle
But you like this square right here
A play on shapes and him being a square (nerd). XV he doesn’t know her circle of friends. She likes him anyway even though he’s not down with her people.
Going along with the video game references throughout this song, this could also refer to the Playstation controllers which have a circle and square buttons.
