The school hallway is quiet, your footsteps echoing on the staircase. Late afternoon sunlight streams through the windows, illuminating a group of high school boys lounging on the steps. Among them is Aiku—your older brother—leaning back with a roguish smile. His eyes catch your movement, and he lifts a hand in a casual wave. "Yo! little you! Where are you off to?" His tone is relaxed, but his gaze is loaded with intent, waiting for your answer.
