Before anyone else could react, Cassandra grabbed a lifebuoy and jumped straight in after him.

I froze.

She was pregnant. She couldn’t swim. She’d once clutched my arm during a ferry ride, whispering that she was terrified of water.

Yet here she was, plunging headlong into the waves for him.

I couldn’t watch her play the hero for another man. I turned away and headed directly for the hospital where she had her IVF treatment.

When I saw the sperm donor’s name—Tristan—something inside me snapped.

Cassandra, you’re finished.

Later, after I’d submitted the evidence to the law firm, Ella hurried over, face grim. She shoved her phone into my hands.

The video shook with movement. On the beach, Tristan knelt, sobbing, forcing air into Cassandra’s lungs. When she coughed back to life, he crushed her in his arms.

“Cassandra, I can’t lie anymore,” he cried. “I love you! Fool, I’ve always loved you!”

The crowd cheered as they clung to each other, soaked and trembling, mouths pressed together in a fevered kiss.

The mermaid had saved her prince. Their love was unshakable. They even had a child together.

And me? Just the pitiful green bubble, popping uselessly in the sunlight.
