Angelic Academy (Rewriting)

Something had happened that day. Something had changed. This was no longer the Cass she knew, he was Dark, unlike the happy, strange boy she had known since forever. He had always been so focused on protecting her, saving her, and now he had taken the plunge. She was supposed to be this way. She was the special one. The one destined to end the Never-ending war. But how had he become this way? How did an angel fall so hard?
