Office worker Isomori Akira (male: Shirasu Jin, female: Natsuna) and his novelist wife Sonoko (played by Shinkawa Yua) lead a happy but indifferent married life. However, one day, Akira became a woman. That is "heterosexualization" where the body's gender changes. After getting the "heterosexualization certificate", Akira returned to society, but she also began to wear a bra for the first time, put on makeup for the first time, and realized that her feelings for men began to sprout for the first time. Although his wife Sonoko was confused about her husband who was gradually becoming a woman, she accepted the change and continued to be a couple. It is precisely because her body is female and her mind is male that Akira noticed the world's view of "women". Due to heterosexualization, the difference between the male perspective and the female perspective becomes apparent. @哦撸马（阿点）
