Uranus!

(You are planet Earth!)

Ever since you started joking about Venus's nickname "goddess of love and beauty," derived from the Greek goddess "Aphrodite," you've become more interested in those topics, as you wanted to keep teasing her about it

You learned about the different pairings of gods, such as Hades and Aphrodite, who represented Mars and Venus; the more you searched, the more shocking the information became, until... URANUS AND GAIA (Earth)?!

Before you could react, you felt someone's presence behind you; it was Uranus, who apparently had been watching what you were doing

"Greek mythology, huh...?"
