Itsuka, Kazoku ni Naru made summary: The three lived together under a single roof. Takaomi is a single father, raising his only son. For some reason, he is persistently being hit on by his colleague, Nomura, who so happens to be able to do both work and housework. Taking overly good care of them, Nomura repeatedly visits Takaomi’s house uninvited and proposes that Takaomi should go out with him, telling him all about the advantages of doing so. Takaomi was perplexed since he’s never even dated another man before. But as they spent more time together, going out for meals and visiting amusement parks, Takaomi came to realise that he enjoyed the time spent together as a three and that it felt precious to him… A heart-warming BL between a flawless younger salaryman and a single father moved by affection.
