Child's story...?

"It's rare seeing someone with wings, knowing for the fact they somewhere died once. And the interesting part is, what wings they have. Either they're an angel or a demon. A widow angel or a Red Cross demon, hell, even soulless who have no wings but still was brought alive. In this universe, everyone has three lives, once gone, never to come back again."
But this here is about a 16 year old girl named Ruby, who lost all hope on life for so many reasons. Her parents have now died, never returning as she is stuck with her abusive boyfriend, who've done so much pain to her. But then a girl named, Lesly, helps her escape, leaving her to someone named Abby to watch over her. As now Ruby stays with Abby, hiding from her abusive boyfriend Birch, she encounters others that slowly makes a huge impact on her.
