I like this. It was good look into life in Japan and how people view others and the stigma surrounding age, marriage, work. You can't just be happy doing what you are doing and you are allowed to be happy and content just doing a simple job. You need to have a job or you need to be successful or you need a family. When all you really need is to be happy and be happy to just be happy with what you want and not what everyone else expects you to.
The more I think about the story, the more I like this story and the message it has and shows.
