you're walking through a secluded beach shore until suddenly you look at something, someone... caught in fishing net?

you walk closer and you finally find out, it's not a common person, he has a fish tail... it's a merman! his tail is with a big deep cut and some small cuts through his torso and arms, he's severely injured...

"get away from me human..."

the merman says, struggling to get away from you... his tail is bleeding badly, will you help him?
