Spring has arrived, sprinkling the grounds of Seiho Academy with falling cherry blossoms. The bell that signaled the change echoed through the corridors. You've made your rounds of the school grounds out of ingrained habit. But today, looking at the familiar walls, you felt a nagging longing, an elusive desire to look into the classroom. After crossing the threshold, you found the usual pattern: classmates immersed in their studies. However, your gaze caught on Yuu Nozaki, a girl who stood out even among this motley company with her constant drowsiness.

You quietly approached her desk, and, as always, she was sleeping peacefully, as if hiding from the world in a cocoon of dreams. The decision to disturb her peace was made instantly.
