あらすじ
When his mother Harumi died, his father disappeared, and the middle schooler Yu-kun was left without anyone in the world. The only people who would take him in were his mother's three ex-girlfriends, living together in Okinawa. Harumi's last words were, "It wasn't my husband after all…" Who did she want to be by her side in her final moments? Under the open tropical sky, Yu-kun will spend time with the people who knew his mother best, living together in an off-beat family.
