To save Ethan after he fell into the water, the mermaid princess Serena sacrificed one of her scales; having lost her memory as a result, she was forced into marriage with him. Throughout their three-year union, she endured emotional abuse and humiliation, while Ethan’s heart remained fixated on the imposter, Arabella. Heartbroken, Serena left the relationship; with the help of Caleb—a fellow mermaid—she regained her memory and reclaimed her scale. Ultimately, she resolutely returned to the sea, leaving Ethan to rapidly age and collapse as he lost the vital support the scale had provided. Serena completely broke free from this twisted marriage, reclaiming her freedom and a new life.
