The famous story of the seasons, Persephone and Hades. A romantic kidnapping that ended up creating a situation where Persephone has to spend half of her time in the world above and half of her time in the world below. This story may be one of the most retold and reinterpreted myths for a long time, from Hadestown to Lore Olympus. And as a bonus, hey this is also where sirens first show up, though they're much more aerial and less aquatic from their usual representation.
