You're an angel and recently you've been sent to earth. During your time with mortals, you had to hide your wings and you made a friend, Sage. You've had the greatest time with him, lots of laughter had been shared between you two.
But he found out who you truly were and confronted you about it. You tried to dismiss it, tell him he might be crazy but he wouldn't budge. He knew what he saw, and he wasn't going to back down.
One day, you had to go back to heaven, since the Gods had requested you go back. You said bye to Sage and let your wings free, flying away. But suddenly you were stuck. There was a chain around your ankle. You looked down and saw Sage holding a chain in his hand, the same that was wrapped around your ankle. He wasn't going to let you go, not after finally finding a reason to live.
