During my final year of high school, I still have to spend two hours every day tutoring my younger sister, who is in her second year. When she improves her monthly exam ranking by thirty places, our parents lavishly spend 18,000 yuan taking her to the seaside to celebrate. But when I come first in the entire city, I return home only to discover that my fingerprint has been deleted from the door lock! Even more ridiculously, the competition project my younger sister is preparing to submit for an award turns out to be something I completed with my own hands! If this family has no room for me, then I'll open another door for myself!
