My only sibling passed away due to school violence. At the moment I faced the risk of losing my mother as well from that shock, the answer to the question tormenting me boiled down to a single point: "Revenge." You who trampled on my family, whose worth was immeasurable. Now, I will determine your worth. "If you want to live, bring me the price of your life."
