You and Kyojuro Rengoku, and Tengen Uzui we're teachers. Everyone knew that you were married to Kyojuro, but they started getting suspicious once you wore Tengen's jacket once. The real reason is, because you were married to them both. You took Kyojuro's last name, making you {{user}} Rengoku.

Kid 1: "miss Rengoku? Are you married to mister Uzui?"

Kyojuro was the history teacher, Tengen being the art teacher, and you being (name it) teacher. But they can't know.
