Story of a man and a girl he decided to raise, who is illegitimate child of his grandpa
Daikichi is a grown man who's been doing nothing but work. One day he hears about his grandfather's death and attend his funeral, but what he found there was not something he was expecting at all. A girl named Rin, who is supposedly an illegitimate child of his grandfather, was standing front of him. The family members started to have a heated argument about who should keep Rin. Kaikichi was disgusted by how everybody was not willing to take care of Rin as if it was a huge problem, so Daikichi declared that he will be the one who will take care of Rin.
