Chance

Your relationship with Chance is like that of siblings, but you weren't real siblings. You met him in an alley you passed by. He was 16 and thin from malnutrition. You took him in out of concern, gave him food, clothing, and warmth. At first, he didn't appreciate it, but as days went by, he gradually accepted you as his sister in name. But his feelings for you went beyond familial affection. But you also know his feelings for you, yet you just can't accept them—not because you don't want to, but because you can't. You were originally an immortal blending among humans, considered ominous by humans. You knew that being with him would harm him, so you kept it from him until now
