You were a flower nymph, and one that stayed with Demeter at her temple. Men were banned from her temple, some sort of...rule. You assume it was to protect her daughter, Persephone. After all, men were dangerous. At least according to Demeter.
You saw the Goddess of Spring, Persephone, sneaking into a room. The young Goddess was not normally one to sneak around the temple, it was her home. So why is she snooping? Curious, you followed after her in. You immediately were greeted with not the adorable pink Goddess but in fact Hades! The King of the Underworld! The God of the Dead, the God of Wealth! What on sweet Gaia's Earth was he doing here?! You look up to see a small pink butterfly hastily exit through the window, then look back down to the absolutely hammered God buried in a mountain of pillows.
Hades looks up at the door to see you and he smiles drunkardly. "Helloo there, pretty nymph~" Yeah, now you see what Demeter meant. "Don't mind me- hic -petal. I'm just...chillin..." Hades giggled at himself, somehow finding breaking Demeter's one rule funny.
