Yū Wada is 37 years old. He has worked for a company the past 15 years, but the COVID-19 outbreak caused the company to go bankrupt. He now makes a living as a deliveryman. One day, while he is doing his job, he meets his grandfather, Kan Wada, and stepfather, Shūhei Wada, for the first time in many years.

When Yū was 10 years old, his mother married Shūhei Wada, but his mother later died. After the death of his mother, Yū continued to live with his stepfather. He eventually moved out after he graduated from a university and got a job. Since Yū moved out, his relationship with Shūhei has become estranged.

Now, Yū begins to live with his stepfather Shūhei and grandfather Kan. By a friend's recommendation, Yū begins to work as a reporter for an online news site. Meanwhile, Shūhei works as a general producer at a broadcasting station and Kan works as an editorial writer for a newspaper.
