After Getting Together with the Fake Crown Prince, I Sink into Passion Night After Night

[Interstellar + ABOE + cold and ruthless top + vengeful bottom + enemies to lovers + love and hate + merfolk + equally powerful leads] Bai Ren, crown prince of the Xingmian Empire, is cold, ruthless, cruel, and bloodthirsty. Known as the “Tyrant,” his brutal methods strike fear throughout the Federation. On the first day after the armistice is signed, Bai Ren is exiled to Motak Star on charges of XXXXXXX. To make a comeback, he lays down three rules for himself: 1. Keep your head down. 2. Keep your head down. 3. Keep your head down. But in the very first second after stepping off the aircraft, he breaks all three. Si Li leaps down from a tree in a white-and-gold Federation military uniform. Silver hair and silver eyes, with a striking figure that’s impossible to look away from. “Well, well. If it isn’t our beloved crown prince. How did you end up in such a sorry state?” Bai Ren gives a cold laugh, furiously crosses out the three rules he just wrote, and replaces them in bright red: 1. Seduce Si. 2. Make Si yours. 3. Have Si a thousand times. In Bai Ren’s eyes, Si Li is a snake-hearted schemer, vicious and ruthless, with nothing going for him but his good looks. In Si Li’s eyes, Bai Ren is violent, arrogant, and ill-mannered, with nothing much to offer besides his strength. An accident during their exile triggers an unexpected secondary-gender differentiation, and the two become entangled. In the pool, Bai Ren transforms into a mermaid. His tail wraps around Si Li’s waist, and his scales brush against Si Li’s skinned knee. “Insult me again. Do it one more time.” Many years later, a reporter asks, “Your Majesty, how did you manage to win over General Si Li, that unattainable flower on a mountaintop?” Bai Ren: “An unattainable flower on a mountaintop??? Si Li? Who’s the one secretly rubbing up against me under the imperial robe right now?”
