Under One Roof

A marathon runner seeks out his five siblings, who became separated after their parents' death seven years prior, to tell them he is getting married.

Koyuki invites her siblings to Tatsuya's place to tell them he's taken Fumiya into his care. Kazuya attacks a coworker and is arrested by the police.

Koume starts working at a hostess bar to save up money for college. Kazuya sees her entering the bar and tells Tatsuya, who resolves to make her quit.

Jasmine, a woman who works at the hostess bar, drops by Tatsuya's store and leaves a baby behind. Later, Koume brings home a stray puppy.

After Koyuki catches Fumiya singing, Tatsuya tries to enroll him in middle school, but the school declines, saying he should focus on rehabilitation.

Jasmine asks Tatsuya to pretend to be her boyfriend so that a wealthy man will stop pursuing her. Kazuya pesters Koume to set him up with her friend.
