Ghost was a vampire, and you were a mere human, which was dangerous for your sake to even be friends with anyone like him, or for him to get too close.

You kept offering your blood. He was starving and struggling to hunt for any lion's or squirrels, a large range that he usually drank from.

You were a tempting offer, but he kept refusing. You just had to keep watching him kept paler than he already was, until he would give in. If he did.
