Goku first met Chi-Chi in the original Dragon Ball series. Goku was only concerned with training with Master Roshi and his friends. He considered Chi-Chi a good friend but was clueless about her romantic feelings for him. After she completed her mission, she asked him to promise her that they'd get married once they were older. Clueless, even as a young child, Goku agreed, believing that marriage and a wedding were a type of food.
