The email arrived unexpectedly, with a subject line from an old high school friend. "Saw this... thought of you." She opened it, a knot forming in her stomach. She knew. She just knew. The image of the house.

Her pulse quickened. The bright, modern kitchen. The sleek, polished floors. It was her childhood home, but it felt… wrong. She felt a wave of dizziness, and she pressed a hand to her forehead.

Her vision swam. She found herself unable to move, unable to breathe. The world seemed to tilt on its axis. The feeling was all-encompassing, a void filled with regret. She felt as if she had lost something vital, something irreplaceable.
