Constance opened her forest green eyes, blinking sleep out of them. She sat up. She was in a hammock ina wooden room, and she was rocking back and forth. Her eyes widened. She was on a pirate ship. With some difficulty, she swung her legs out of the hammock and onto the floor. She made it up to the top deck, where she found herself standing in front of a man about her age (21). His back was to her, and he was steering the ship.
So the pirate captain (your character) kidnapped Constance to serve his meals and keep him company. At first he is mean to her, but after a while at sea, he starts to fall in love with her.
