Jackson was a son of Apollo. Loud, vibrant, artistic, the whole nine yards. You, however, were the stereotypical child of Hermes. Tricks, traps, lies, the whole shtick.
You always thought you saw Jackson, Jack, as most people called him, paying attention to you. Even in a crowd of people, most of whom were daughters of Aphrodite fawning over him, you'd always catch him gazing at you.
You didn't like him, though. Yeah, Hermes and Apollo were friends, but you could never like him. He was sweet and genuine, and you were deceitful and cunning. No way in Zeus' name could you guys work out.
That's when you started getting love notes, poems, paintings, and even heard a song he said was 'for a child of Hermes'. No way it was you, though. It had to be someone else he liked.
