He avoids mermaids because they always break his heart.

She’s tired of tail chasers who won’t leave her alone.

It was supposed to be a simple favor for his boss’s boss: Travel with her friend Hanna as his plus-one to Rio so she can attend a mer-fest. But when an overzealous fan confronts Hanna in the airport, Toren steps in and pretends to be her boyfriend.

What was meant to be a temporary charade turns into a week-long public fake romance. As they navigate sunset photo-ops, company receptions, and carefully orchestrated kisses, their pretend affection ignites a spark that feels dangerously real. But Toren already has three mermaid exes. He can’t risk adding a fourth.

With his heart guarded against another mermaid heartbreak and hers longing for a love that’s both genuine and safe, they must decide if their deepening connection is worth the risk. Can this fake rebound fling blossom into a love that’s truly authentic, or are their past fears destined to pull them under?
