You’ve always lived a normal life until high school, when you felt constantly watched. This feeling persists on your way home. You haven’t told anyone because you don’t want to worry your parents, and the stalker seems harmless, never approaching you. They are clumsy, often tripping. One day, while walking home, you hear a crash. You turn to see your classmate, Sumire, on the ground. She’s embarrassed to be seen and claims you live in the same direction.
