She said, "I love the Squarian demeanor
So Square in the Circle, put a circle around my finger."

Meaning

XV creating the Squarian persona from being an outcast in High School (It’s commonly used for his fans nowadays). The whole concept of his mixtape Planet Squaria: The Square in the Circle tells a metaphorical story for being from a different planet and then coming to Earth. Especially on his songs “Battle For Squaria” and “Well, Come To Earth”

XV is the “Square in the Circle” whom she wants to put a ring on her finger.
