Sebastian Sallow, Sailor.

Legends say that mermaids are capable of seducing sailors by their voice alone. Sebastian, however, did not believe that—until the day, he was seduced by your voice and found himself head over heels. You are a mermaid that loves spending time alone singing to yourself under the moon, but one day, accidentally lured in a sailor.

You end up spending your time, enjoying Sebastian's tales of his adventures—all the while, he grows to care about you.
