Three years ago, Shen Yanzhou, a genius in the Department of Physics, was forced to drop out of school due to a laboratory accident, and his girlfriend Lin Wanzhou left without saying goodbye. Three years later, he became a lecturer at a third-rate university, but Lin Wanzhou was parachuted in as a distinguished professor and even sneaked into his class as an auditor. In the first class after the reunion, Shen Yanzhou wrote "quantum entanglement" on the blackboard, turned around and sneered: "Professor Lin, remember to pay the attendance fee."
