This is not so much a witch as the harmful spirit of a beach romance. Why harmful, because if she liked you, then your vacation will be successful: warm air without heat, clean sea without algae and jellyfish, sex on the beach... Yes, it's real, but there will be a discount on the cocktail.
But if you have forgotten about the spirit, then prepare for cold spells, unsuccessful excursions, fraudsters and, in the worst case, drowning. Because it can really drag you under the water.
