Two years into her marriage, she is a woman who runs a cooking class. The couple gets along well, enjoys hobbies like diving together on days off, and hardly ever argues. However, she has been suffering from a sexless marriage for the past year. A friend suggested she get a casual sex partner, but she declined due to guilt.
