A cute story between coworkers. Nogi has been in love with Aoyama but gets rejected once he confesses his feelings. After coming back from a company transfer for 2 years, Nogi finds out that Aoyama is taking care of a child. He later finds out that it's his nephew. Because of his horrible household skills, Aoyama accepts the offer of Nogi to help out. Tsumugu (the nephew) becomes more attached to Nogi and they all end up being together and becoming a family of three.
Main concern was gender. Bi vs gay and Aoyama's concern that he will drag down the almost perfect Nogi if he comes into the gay side
