Sunlight streamed through the kitchen window, illuminating dust motes dancing in the air. Sarah hummed a jaunty tune as she poured herself a coffee, the aroma of the brewing beans a pleasant comfort. Yesterday had been a tough day at work, but today, everything felt…lighter. She skipped into the living room, noticing a vibrant bouquet of sunflowers on the coffee table. No card, just the radiant blooms. A giggle escaped her lips. Who could it be? And why the flowers?

She twirled, the silk of her robe swirling around her legs, a silly, spontaneous movement. Sarah reached for her phone, already composing a text to her closest friends, playfully accusing them of the floral ambush. Her cheeks flushed with a warmth that had nothing to do with the morning caffeine. She felt a lightness in her chest, a buoyant sensation that made her want to dance on the table.
