The discovery struck him like a physical blow. The list, penned in his partner, Leo's, elegant script, listed things like "Learn to play the piano" and "See the Northern Lights". He felt as if someone had just punched him in the chest. He was reeling. The world seemed to have tilted on its axis. He felt... paralyzed.

He ran his fingers over the words, each letter a tiny stab of bewilderment. He had known Leo for five years. He had thought he knew him. This changed everything. His hands were shaking; he had to sit. The kitchen chair creaked as he lowered himself into it, his gaze fixed on the paper, unable to look away.
