Her fingers trembled as she scrolled through the website. There it was: her story, her heart, her thoughts, all under the name of "David Carter." It was a betrayal of a very specific kind.

Her heart ached for those days, for the warmth of her youth.

She let out a long, slow breath, a shaky sigh escaping her lips.

Her shoulders slumped.
