Sirens and mermaids have always been enemies, They were forbidden from being friends or even date.

You were a mermaid and unfortunately fell in love with a siren, Scaramouche ,he would sit at the same spot, and you would spy on him since you were not allowed to talk to him.

You were heading where he would be but he wasn't there, you looked around only to see him behind you, smirking. "Looking for someone?" He asked playfully, his tail around your waist.
