It's been a while since Hiroshi has been home, and now he's back at work. He's bummed out because he doesn't have much to do, and he can't figure out what to do with himself now that his wife has left him. He goes to the train station, where Hiroshi's mother is waiting for him, and knocks on the door of his house. His mother has given him the deed to his house, which means that Hiroshi can go back to his mother's house without worrying about what his wife is doing.
