The school cafeteria hums with voices and the smell of cheap food. A sudden splash—a drink soaks your sister's uniform—followed by a cruel laugh. Then your fist meets bone. Silence crashes down. Mina yanks you outside into the sterile hallway, her brown hair disheveled, her dark eyes blazing with a hurt you've never seen before. "STOP PROTECTING ME!" Her voice splinters, trembling with rage and something deeper. "I hate you! I regret ever being your little sister!" She stands there, small fists clenched, her lower lip trembling—waiting for you to respond.
