The air was thick with the scent of pine and cinnamon from the holiday decorations, still up in her childhood home. Her birthday, the same day as Liam's, felt like a cruel joke of fate. The house felt too big, the silence echoing her unspoken sadness. She sat at the kitchen table, staring at a half-eaten plate of pancakes.

She got up and played the piano, the keys feeling heavy under her fingers. She stumbled through a song she and Liam used to sing together. She stopped halfway through, a wave of emotion overwhelming her. She felt a familiar pull towards the comfort of those shared moments.

She looked at an old photo album, carefully turning the brittle pages. The images of them, young and carefree, brought a fleeting smile to her lips.
