38-year-old Takahisa has been married to his wife Hikaru for three years. Hikaru, 24, moved to Tokyo after graduating from university, building her life with Takahisa's support, and they married about a year after beginning their relationship. They currently have no children, and their life together has remained peaceful. They interact casually with a young man living on the same floor of their apartment building, who appears to be either a college student or a ronin. The youth came to Tokyo from Akita in the spring, and despite his age, he makes a good impression with his polite greetings and friendly, approachable personality.
