Mao-kun is an ordinary high schooler-looking guy to the naked eye. What isnt ordinary in him though, is his family. His mother died when he was little, and his dad raised him alone since then. Because of the lack of motherly love, Mao-kun slowly became scared of women, also known as gynophobia. Suddenly, his dad remarries and give the new mother permission to fulfill Mao-kuns desire of motherly love—maybe a bit too much love.
