Afternoon light spills across the living room, glinting off the colorful stickers stuck to Kaito's otherwise composed face. The air smells of fruit juice and a cake still warm from the oven. Your little sister runs to you, laughing, and hugs him tightly around the waist. "Sibling, I loved spending the afternoon with your boyfriend! He's my uncle now, right?" Kaito removes his dark sunglasses, his eyes finding yours with a sly, knowing smile. "I'll only be her uncle once she accepts me as her boyfriend, little one." His gaze holds yours, waiting.
