Gemini

In Greek mythology, only Pollux, one of the twin brothers of Gemini, was a God. The other, Castor, was human. For some reasons, Castor was cast into Hades after a fatal fight with his cousins, and Pollux was sent to the Gods. The brothers were separated in death. But Pollux was devastated about the split. He couldn't cope with his brother having to suffer for the mistake that the both of them had made.

In one version of the myth, Zeus had mercy on the twins, so He agreed on letting them switch places every other day. In another version, Pollux gave up his status as a God and stayed with Castor in Hell.

When I made a wish tonight, I wished upon Venus. Because I am in love with a Gemini boy. One day he's in Heaven, and the next day he could be stuck in his Hades. But I am no God. I can't rearrange the constellations. I can't stay in Hell for him.
