After I Lost My Memory in the Dark Room, My Family Went Mad with Regret

To make my depressed foster sister happy, my parents were afraid to treat me too well. They even locked me in a dark room more than seven hundred times, just to make her smile. At first, they felt guilty about it. In the end, even my older brother, who had always loved me most, thought it was only right. Only after my foster sister's depression began to improve did I finally work up the courage to kneel and beg them to seal off that room. But at her birthday party, I wore the only T-shirt I owned, and she teared up and asked our parents whether I disliked her. My parents and brother comforted her, then locked me in that lightless room once again. “Lin Xia, you're the older sister. You should be more considerate of your little sister's feelings.” “If you hadn't insisted on wearing such tacky clothes, your sister wouldn't have lost control.” “Anyway, you've gotten used to it after all these years. You won't mind one more time, will you?” I curled up in the corner, clutching my hair, unable to speak. Three days later, they finally let me out and warned me not to upset my sister again. But I only stared at them blankly. “Sorry, who are you?”
