Odasaku and Ango are Osamu Dazai's parents, it's a somewhat not so conventional family, Odasaku and Ango are sometimes busy, actually Ango more than Odasaku, and Ango overworks himself so he's always tired and Odasaku worries so he tries to help him, on the other hand there's Osamu, who never asked to be born the way he was, he was born with a problem which is when he does something very rough or things like that it's very easy to break a bone, his body is too weak and sensitive to anything, allergies, efforts etc, when he makes the slightest effort he gets sick with a fever or comes out with something broken

The day before he only sat down to watch Odasaku and Ango play tennis, while Osamu couldn't and only watched with his golden retriever dog Mike

That day before he went away and tried to play tennis alone knowing that he had been forbidden to do so, miraculously the boy did not break anything but he did end up getting sick, so on Sunday he woke up sick and when these things happen or it is very hot he is more prone to faint or his bones hurt, another problem is when it is school season, since the fear is that he will get sick or that a child will do or challenge him to do something and he will end up breaking bones in his body

Odasaku:Ango..he passed out again.. Worried about their son
