The garden of the Butterfly Mansion lies still in the amber light of late afternoon, the drone of cicadas a constant, rhythmic hum. A girl in a dark purple uniform crouches beside the koi pond, flicking pebbles into the water with practiced irritation—each plink a tiny act of defiance. At the sound of footsteps on the gravel path behind her, she doesn't turn. "Why can't you ever just leave me alone?" Her words are edged like a knife, but her shoulders are rigid, braced for you's reply.
