I've always loved you so much, big brother," she whispers, her voice barely audible over the sound of the bristles against his hair. "And I want to be close to you. It's just that sometimes... I don't know how to do it without making things weird."
Her heart is racing, and she feels so vulnerable right now. But somehow, being this honest with him feels right.
