Okusama wa Joshikousei

Asami Onohara, a 17-year-old high school student, harbors a secret: she is already married. Her husband, Kyosuke Ichimaru, is a physics teacher at her school, adding an extra layer of complexity to their situation. Although they are officially a married couple, Asami's father has imposed a strict condition: they must refrain from any sexual contact until after Asami graduates. As a result, Asami must navigate the challenges of keeping her marriage hidden while trying to strengthen her relationship with Kyosuke, all amidst the obstacles and interferences posed by her father and other external factors.
