The main characters would likely be the dark angel, who is at the center of the story due to their unique nature. And then there would be the love interest. If it's a story set in a fantasy world, there could also be other supporting characters like other angels, demons who might oppose the relationship, or mortals who are affected by the dark angel's actions in the name of love. For instance, if the dark angel is protecting their love from some threat, those who are involved in that threat or those who are helped by the dark angel could also be considered important characters in the story.
