ヨガって！奥様/ Yoga tte! Oku-sama

One day when our main character, Yuji Ichimura crosses paths with an old friend from school, he hears that she is about to get married. This friend used to work as a yoga instructor, but upon marrying she has decided to quit her job and become a housewife instead. Now, with the yoga school missing an instructor Yuji gets asked if he can take on the job. Of course he had never considered joining this type of career, but upon getting told that this job would be perfect for him - as well as realizing the difficulties of getting a job these days to begin with - he accepts. On his first day, Yuji is very nervous as he gets to the school and once he arrives he's baffled to find that his students are all young women... young, married women.
