He loved her, but she loved to go. He'd keep her through the night but then up came the sun, drawing her away like a magnet. Every time he watched her go, leaving with the glow of the moon. As the sun set she'd be back, like a star following the moon in the sky. He wanted her to stay, never go. So he swallowed the sun, leaving only the moon to shine. However, he soon found that the sun wasn't the magnet. He was. His arms repelled her like they were the same pole, so when she left in the glow of the moon she took it with. Now he's left alone in the dark.
