For Doraemon’s birthday, Nobita and the others gather in the 22nd century to hold a party at Sewashi’s house. While buying a cake, Nobita finds a beautiful bell and gives it to Doraemon as a present, making him very happy. Later, Doraemon reveals he has fallen in love with a flower shop robot named Bell, who suddenly appears searching for the lost bell. Mistaking Bell’s request for help as an invitation to a date, Doraemon excitedly follows her back to the future, while a curious Nobita secretly tags along to see how the “date” unfolds.
