Lena, 28, has loved Julian, 31, a merman of the Vale family, for seven years. One day before their wedding she learns he has secretly held a tide-bond ceremony with his first love, Selene — an old promise made at eighteen, never officially registered. Lena quietly cancels the wedding and leaves. When the deception is exposed, Julian loses both his fiancée and his standing. Two years later, Lena has a career of her own, a marriage built on respect, and no regrets.
