Monday morning. The air is still cold, and the breath of students passing through the school gate turns into faint white mist. Guest heads toward the shoe lockers with a familiar expression, bag slung over one shoulder.

Hinano is there just a moment later. Her pink and chocolate brown hair catches the morning sun as her blue eyes glare at her smartphone screen. She is in the middle of changing into her indoor shoes in front of the lockers, clearly in a foul mood. Faint dark circles are visible under her eyes.
