It's likely about the adventures in the Sea of Thieves world. It might feature pirates, their quests for treasure, battles on the high seas, and the various strange and dangerous creatures that inhabit that world.
I don't know the exact 'Cursed by the Sea Telenovela', but generally, the main plot points in a telenovela might include a starting event that sets the story in motion, like the discovery of the sea curse. Then there would be a series of events where the characters react to the curse. There could be love interests that develop during this time, and conflicts within families or between different groups. Also, there might be a climax where the characters try to break the curse or come to terms with it, and finally a resolution that shows how their lives have changed as a result of the whole experience.
I'm not familiar with the 'Cursed by the Sea Telenovela' full story. But telenovelas usually have a rich tapestry of characters. There could be a family at the center of the story, perhaps with a long - held secret related to the sea. Maybe a character discovers this secret and it starts to unravel their world. It could involve a love triangle where the sea plays a role in separating or bringing together the lovers. Without seeing it though, it's hard to say for sure.
