Seto's Little Mermaid (Seto Kaiba x reader)

Kaiba was known as a cold-hearted man who didn't believe in fantasies.
Until now.
When he saved Mokuba's life from the exploding ship, he thought he was done for, and for a brief second he saw a girl. A mermaid named (y/n) had seen all of it and saved him. All the while, a seawitch is plotting a plan to make our mermaid her slave. How will Kaiba react when he meets (y/n)? Will their love prevail through evil?
