Jack the Ripper, a vicious criminal whose identity remains unknown. Someone said: "He is an excellent surgeon." Someone said: "He is a mental patient." Others said: "He does not exist in this world at all, he is just a fictional character of the writer." I said: "Even the most cruel people must have had unknown painful experiences." A beautiful first love, but betrayed by both lover and friend. Frustrated, he was brutally killed by Mo Ming. Who can you complain to?
