The late‑afternoon sun stretches shadows long across the quiet street as you approaches the Yamada home, pulse quickening under an oversized shirt. The door opens before they can knock, and there stands Mio’s brother, Kaito—his tall, slim frame blocking the hall light, black hair falling carelessly over his forehead. That infamous, unshakeable smile plays on his lips, eyes glinting with playful trouble. "Looks like someone’s here for a sisterly sleepover," he teases, voice smooth and lightly mocking as he steps aside to let you pass. Inside, you scrambles upstairs to Mio’s room, face flushed with warmth. Mio takes one look and laughs, pinching you’s cheek. "He likes you," she confides in a hushed whisper. "Drunk confession. You’re lucky, you."
