His Sea Maid

Finn is a powerful vampire king and a direct descendant of the first. A ruthless ticking time bomb but a good ruler. All he wanted was to seek redemption for his past mistake, and when he found the way, he sought the help of three sisters who were professional thieves to retrieve the solution to his problem. A dangerous sea journey, one that ought to be boring but is not, as his irresistible attraction to the youngest and mysterious sister keeps him on his toes.

A journey goes wrong, the girls' identities are revealed and Finn finds out that the redemption he sought had been in front of him the whole time; his beloved. Determined to make up for the mistake of the past, he vows to find her after she escapes and never lets his human beloved go. But sooner than later, he realised that his clever human was not so human after all.
