After Killing the Villainous Merman, He Proposed to Me

An Shi transmigrated into a book and became a cannon-fodder character who shared her name.

The original owner of this body was a lecherous researcher who coveted the villain's beauty. Mistaking an abyssal fiend for a simple little mermaid, she designated him as her "private research project." In the end, the villain tortured her to death, slicing off her fingers one by one.

The mermaid sat in a glass tank, eerily beautiful, smiling at An Shi with an obedient, alluring smile that concealed murderous intent.

An Shi: ...I really am a respectable researcher.

She had no illusions about the possibility of reforming the villain.

An Shi did her best to cling to the original owner's persona and put on a spectacular performance, keeping her guard up and desperately recalling the original story as she tried to plan a way to survive.

At last, the day the villainous mermaid escaped arrived.

His sharp claws playfully drew a bead of blood from An Shi's neck, while her dagger plunged into his heart.

Lan Miuhe Si: ?

The woman lowered her lashes and calmly delivered another blow. When she raised her eyes, not a trace of her usual frivolity or arrogance remained. "I've been waiting for this day for a long time."

After tossing the mermaid's corpse into the sea, An Shi breathed a sigh of relief and happily prepared to start a new life.

But she didn't know that Lan Miuhe Si hadn't died.

The deceived devil escaped death and, just as in the original story, took human form and infiltrated the empire, transforming himself into a duke. Then, under everyone's gaze...

He proposed to her.

The young woman was too shocked to speak. The handsome young man wore a wicked smile as he kissed the fingers clenched in his palm.

"Sister, we've met again."

This time, don't even think about escaping.

He was a vengeful abyssal hybrid, a fiend by nature.

So he would repeat what this liar had once done, only more cruelly, and watch her beg and weep under his torment as he tore away her composed mask. That would make his "revenge" all the more entertaining.

But as the days went by, An Shi gave up resisting.

The empire remained peaceful, and she was still alive and well.

Only at night would an icy, magnificent fish tail entwine around her, seeking pleasure, while cold, damp breaths drenched her in the intoxicating aura of the deep sea.

"...Weren't you, weren't you going to take revenge on the empire?"

"I was. But what can I do? Now I only care about you, Sister. Nothing else matters."
