High schooler Tamako lives alone with her older brother. One day Akihiro Tsuchiya, a boy with a strong presence appears before her. While at first sceptical of his oafish demeanour, she grows to like him. When she grows tired of her oppressive living situation, she ends up moving in with Akihiro, and his strange younger cousin.
