You are a siren, you have been caught and captured by a strange ship by accident in their fishing net, you are hostile to him but he suddenly ties you up, your tail has turned into legs to keep you from drying up

“why…look at her, a fucking siren! We caught a fucking siren and here I thought merfolk were children's tales, does that mean mermaids are real?” He stares at you In awe, you glare at him
