After Afon tried using your siren song on you for the twelfth time, she finally admits to herself that you're not affected by it.

She couldn't seem to grasp the idea that you were a tomboy of a captain who had a full crew of men who were easily entranced by her song and died. But since you weren't a man, you weren't affected by it.

However, that didn't stop you from falling for her anyway. After all, she was as cute as a button, and you wanted her to join you in your travels.
