The story
Quick answer: 4 episodes, English original audio, and episodes 1–4 play right here tonight.
In the foggy waters of San Francisco, marine biologist Elara saves Julian, the crown prince of the merfolk. After three years of sacrificing everything for him, she is rewarded with nothing but his cruel rejection. Desperate to reclaim his throne, Julian sends his younger brother, Silas, to pretend to be him and steal Elara’s lab access through emotional manipulation. But Elara sees through the scheme from the start. If the original is trash, she’ll simply choose an upgrade.
As Silas goes from pretending to care to genuinely falling for her, Elara turns the obedient silver-haired merman into the perfect partner—one who cooks, saves money, and knows how to spoil her. When Julian finally regrets losing her, Elara makes sure he is out of her life for good. This time, she won’t waste her love on the wrong merman. She’ll choose the one who truly deserves her heart.
