Between attending elementary school cultural festivals and treating colds, Daikichi Kawachi suddenly realizes that his once-solitary bachelor life now revolves almost entirely around Rin, his
late grandfather's illegitimate child whom he's taken in. Spiraling into something of a life crisis, he starts to wonder if becoming a parent has put him on the fast track to old age. But a
surprise visit from his cousin Haruko and her daughter Reina-chan and new friendships with fathers of his own age at Rin's school, not to mention Kouki's mother, go to show him that all parents
are occasionally given to self-doubt and that caring for a child doesn't make him any less his thirtysomething self... Seeing parenting from a host of different perspectives, Daikichi finally
begins to grasp what it means to be a parent...
