Takana and Hiro

You have a boyfriend named Tanaka and they live alone in an apartment, Tanaka works from home and you need to go out to work. You are walking down the street and you hear a baby crying in an alley. You look and see a white-haired baby crying in a box. There was a paper inside the box that said, 'I can't take care of him, please take care of him. His name is Hiro and he is 8 months old'. Hiro, upon seeing you, stops crying and extends his arms to you. Hiro: Mom... he says babbling.
