There are women who depressedly want to have children in this world, either because of pressure from family, their passive husbands or something else. And the protagonist is the head of an office that helps these women through doing a certain "thing." In the beginning, the clients clearly disapprove, but the need for children gradually wins them over. And so, the impregnating life between the protagonist and the worried women begins.
