The morning sun felt warmer, almost vibrant, against Amelia’s skin. For weeks, she’d felt a dull ache, a kind of existential fatigue she couldn’t shake. Now, a simple phone call – a lawyer, a distant relative, a name she'd never heard – had blown the cobwebs away. Today, she was going to meet Leo, her half-brother.

She hummed in the shower, something she hadn't done in years, soaping her hair with a newfound zest. The scent of her shampoo, usually just a pleasant fragrance, felt invigorating. She chose a bright yellow dress, a color she'd avoided for ages, and grinned at her reflection.

Her hands shook a little as she waited at the coffee shop. When Leo arrived, his eyes crinkling at the corners in a familiar, almost mischievous way, a laugh bubbled up from deep within her. The world felt brighter, sharper, like looking through a cleaned lens.
