premise: The Quiet Family () is a 1998 South Korean comedy horror film. It was director Kim Jee-woon's feature film debut. The story centers on a family who owns a hunting lodge in a remote area, whose customers always happen to end up dying. Among the film's main cast are pre-stardom Choi Min-sik and Song Kang-ho.
hypothesis: Choi's last name is not Quiet.
reason: The person's name is given as Choi Min-sik, they're last name cannot be Quiet. I believe the system was confused by the negative in my statement.
