We don't really know who invented the first valentine, but it's pretty certain that person was in love, just like the Roman emperor's secretary who loves the emperor's daughter. But how to make her notice him? Give her a gift. And that's exactly what he does, but the emperor keeps intercepting the gifts. Finally, with determination but in great fear, the secretary tells the emperor's daughter he loves her. Well, she loves him too. And that's just what the emperor was hoping for.
