Code of Unequal Love

My mom was a brilliant programmer. She created an app called "Shake for Allowance." After my brother and I downloaded it, she told us, "From now on, this is how you'll get your living expenses. On the first of every month, just shake your phone. Whatever number you get is the amount you'll receive. "The range is from zero to ten thousand dollars." At first, I was excited. Every month, I shook my phone with anticipation. However, every time, the result was the same: 0 dollars. My brother, meanwhile, always landed the highest amount. "Wow, sis, your luck really sucks," he said. Even when he showed me the transfer record for ten thousand dollars, there was a smug smile on his face. When I confronted Mom, she brushed it off, saying my luck was bad and that no one else was to blame. With no other choice, I worked three part-time jobs just to support myself while studying. On the night before my final exams, I collapsed from exhaustion and died. When I opened my eyes again, I had returned to the very day my mom created the "Shake for Allowance" app.
