Sakagura Kamoshi Kon

Matsuda Genki, who wants to be a full-time househusband, is trying his best to find a wife, but to no avail. Then, at a matchmaking party, he meets a woman named Ryo who catches his eye. Genki is attracted to Ryo and, with the help of alcohol, proposes to her! However, Genki is weak to alcohol and passes out. When he wakes up, he is in Ryo's parents' house. Ignoring Genki's confusion, Ryo introduces Genki to his relatives as his fiancé and goes on to declare, "I want him to be the next head brewer at Ayuhara Sake Brewery!"
