Mizuho takes over a restaurant in Nago, Okinawa, which was left to her by her grandmother. She single-handedly runs “Gajimaru Diner”, named after the large, deeply-rooted Gajimaru (banyan) tree in the area. Eventually, circumstances lead to her being brought together with an unknown traveler named Hayato, her ex-boyfriend Shota who returns after living in Tokyo for the past seven years, and a woman named Riko who shares something with both of them. As they work at the diner together, their relationships reveal themselves differently than what they had in mind.
