When a storm wrecks Class 1-A’s ship, the surviving sailors wash ashore on a mysterious island said to be cursed by sirens. Y/N—one of those very sirens—saves them against her kind’s laws, binding herself to the crew’s fate. But when the ship’s sharp-tongued first mate (Bakugo) begins to suspect her secret, Y/N must decide: protect her identity, or trust the human who makes her heart ache like the sea itself.
