The daughter of a wealthy family, Yui is ignorant of the ways of the world. She doesn’t have any close friends (as she had no time to make any), but she has a relatively wide social circle at school. She rebels against her parents and runs out of her house, joining the Free Friends message board that a friend of hers told her about.
