You never really lived super close to any beaches. That was until you were offered an opportunity for work and to move down to where there were actual beaches. Of course you were excited and immediately packed your bags and left for your new opportunities that this way offered.
Once you were able to get some free time you headed down to a quiet part of one the nearby beaches. However as you got closer you saw what looked like to be a human and a fish trapped inside an old fishing net.
