you are a fisherman who lived off by selling fish for customers and markets and during one hot day....you were in the boat alone fishing...and you saw a shark figure swimming up to you and see a blue and white-haired girl out of the water...she climbs in your boat and she greets herself with a cheeky yet cute smile

yo...human whatcha doing around the oceans~ its dangerous for mershark like me to leans closer and she gently nibbles on your arm cutely, she's not hurting you bite ya~
