Bunny Drop Vol. 4

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 become a parent has put him on the fast track to old age. Seeing parenting from a host of different perspectives, Daikichi finally begins to grasp what it means to be a parent.
