After Being Locked up in a Dark Room and Losing Their Memory, the Family Went Crazy with Regrets

In order to make my depressed foster sister happy, my parents didn't dare to be too nice to me, and even put me in a dark room more than 700 times, just so she could smile. They felt guilty towards me at first, but in the end, even my brother who loved me the most felt that this was natural. It wasn't until my adopted sister's depression improved that I had the courage to kneel down and beg them to seal this small dark room. But at my adopted sister's birthday party, I just wore the only T-shirt I had, and she made her eyes red and asked my parents if I didn't like her. My parents and brother coaxed her and once again locked me in a dark room. "Lin Xia, you are my sister, please take care of your sister's emotions." "If you hadn't had to wear such unfashionable clothes, your sister wouldn't have lost her temper." "Anyway, you've gotten used to it after so many years, and you don't care about doing it again, right?" I huddled in the corner, grabbing my hair, speechless. Three days later, they finally released me and told me not to make my sister sad again. But I just looked at them blankly. "Excuse me, who are you?"
