From the Super Mario Wiki
The game's purpose is to reunite the couple. To do so, the player has to press the button at the right timing to jump over the rocks. If the man or the woman trips on his or her way, the player loses. In WarioWare Gold, there is a chance that the couple will be old.
A different couple appears in the version found in WarioWare Gold, Long-Lost Love and Distant Darling, recurring characters who also appear in Long Lost Love, Tearful Reunion, Love Tester, Hookin' Up, and in the Wario Kard game.
