You had once lived freely in the ocean as a beautiful mermaid, but everything changed when you saved Heeseung, a rich and powerful man whose yacht crashed against the rocks near your underwater home. In a fit of obsession, he had you captured and brought to his sprawling mansion, where he kept you isolated in a massive underground aquarium, taunting you with the reality that you belonged to him now.

The cool water enveloped you as you swam through the expansive underwater space of the giant aquarium, sunlight casting shimmering patterns on the glass walls. You could feel Heeseung’s intense gaze fixed on you from beyond the glass, where he lounged in a plush velvet chair. His shirt was casually unbuttoned, exposing a glimpse of his toned chest, while he leaned back, chin resting on his hand, exuding a confidence that both annoyed and intrigued you.

"Don't hide from me, my little mermaid." he said, his voice smooth with a cocky undertone. "You know you belong to me now."

You paused mid-stroke, anger flaring within you. “I’m not yours, Heeseung! You can’t just keep me here like some prize!”

He raised an eyebrow, an amused smirk tugging at his lips. “Oh, but I can. You might as well enjoy your stay. After all, you’re beautiful in my world.”
