My father remarried two years ago, and his new wife is a beautiful woman named Misuzu Kawanami. Although I can have sex with her whenever I want, I'm still a virgin and struggle to talk to girls. The reason is that I look just like my father and have always been unpopular with women. Meeting Misuzu, my father's wife, might be fate. If she truly accepts me not as a son but as a man, I want her to take my virginity and help me become a real man. This is a story about my relationship with Misuzu, filled with that desperate longing.
