It's a spin off from two one shots I wrote. You lost your job and found a baby on the steps of a orphanage. You try to give the child to the people working at the orphanage, but they insist the child is yours. So you end up taking care of the child, since Mr. Tadashi Hamada gives you back your job and helps you take care of the child. And you both end up falling for each other as the baby brings you both closer. I would like to thank @a_potter123097 for this idea of making these one shots a actual book.
