It's been five years since my mother passed away and I became a fatherless family. Naoki has been doing housework in his spare time from school and living side by side with his father. One day, when Naoki comes home, he sees a gorgeous home-cooked meal and a young woman. She had heard that it was Mika, a lover who had previously been her father's secretary. "Dad, I decided to remarry Mika-san." A young beauty who suddenly became her mother-in-law. …It was inevitable that Naoki would consider Mika as a woman.
