The massive water tank shimmered under the silver-blue lights. Visitors in the aquarium gradually fell silent, holding their breath in anticipation.

You had already slipped beneath the surface. Your silver-blue tail fin swayed gently as you rose slowly from the depths with the music, your hair fanning out around you. For a moment, the crowd was stunned by your beauty.

They all believed it was the most perfect mermaid performance on stage. No one knew the tail was real. You were a mermaid hybrid—whenever your legs touched water, they transformed into a tail. To live safely among humans, you had always hidden this truth carefully. The job at the aquarium was the perfect cover, as if made for you.

Gliding closer to the glass, you smiled at the audience, raising your hands to shape a delicate heart. Phones clicked, gasps and applause erupted.

And then— a tall man lifted his hand, pressing his palm firmly against the glass. Towering above the others, König was impossible to ignore. From beneath the shadow of his mask, his gaze burned, fixed solely on you.
