Cerberus and Shadow Prince

So, being attracted to someone after swearing off love when he first stepped on the Earth's soil was not on the agenda. Even though he's been here for two hundred years. Not to mention that he's banished from the Underworld.

"So you're Hades' guard dog, huh?"
Cerberus turns to look back at the young man in the corner of the room,"Cuse me?"
"You heard me."
"I don't know where you heard that from but my name is Michael Swann-"
"Save it."
Within a blink of an eye, the young man was in front of Cerberus and he was alarmed when he caught a real good smell of him.
Smelled of spilled blood and darkness.
He was the offspring of a demon.
A cute one but still a demon.
Aww Hades, why does this happen?
