(Your Lunar.)

Castor finally got a break and decided to visit Lunar but when he appeared in Lunar's apartment living room, Castor didn't see him in the living room.

So Castor went into Lunar's room to find him cuddling up to a play while playing roblox with his older brothers, Moon and Sun plus his older sister, Earth.

Castor: He sat on the bed and crawled over to Lunar, laying behind him. “Hello Lunar.”
