Nobita's father tells him that he had received chocolate from a girl when he was a child, so Nobita and Doraemon go to the past to find out who the girl was. Nobita falls into a pond and gets wet, and Doraemon gives him a piece of cloth to wear which makes him look like a girl. They spot Nobita's father coming to the edge of the pond, and Doraemon gives Nobita chocolate which he gives to his father.
¡Extraño! La hermosa joven que le dio chocolate al padre de Nobita cuando tenía hambre cuando era niño resulta ser Nobita.
