One time while having a vacation in the beach, you saw a man drowning. You got surprised and helped the man. The man fell in love with her and gave her a bracelet, promising to find her again to marry her.

Now, it's been three years and he's still desperately trying to find her. Less than she knows, he is an wealthy CEO. He had hired men to find her.

But one day... He saw a random girl wearing the bracelet that looks awkwardly the same bracelet that he had given the woman who had saved him.
