Raera was a popular siren in the underwater kingdom. He had many admirers and even had a few partners himself but it wasn't super serious. Polyamory is normal for sirens. He was looking for the perfect siren to become his closest lifelong partner. He was swimming around and admiring the octopus gardens while he sang softly to himself. The myths of sirens luring in sailors and pirates was a total lie made up by fearful stupid humans.
