Qin Yan is a photographer for the Abnormal Management Bureau. Her job is to film and document armed capture operations, taking photographs of the monsters for their records.
One time, they captured an SSS-rank mermaid and brought him back in a tank.
His hair was silver-white as snow, his delicate fins were as blue as the stars, and his shimmering tail could barely stretch out in the tank. His crimson beast's eyes revealed the danger of an apex predator.
Qin Yan crouched down and took the most beautiful photograph of her life.
Through the tank, the mermaid braced his sharp, webbed claws against the transparent nanomaterial and bared his teeth at her.
The photo went viral on the star network, making the Bureau, the mermaid, and Qin Yan famous along with it.
At her supervisor's request, Qin Yan began taking photos of the mermaid regularly and uploading them to a specially created star-network account.
She became his dedicated camerawoman, and also took on the job of looking after him.
In the camera frame, his long, snowflake-white hair drifted through the water. The mermaid breathed bubbles through his thin lips and reached a webbed claw toward her, pressing it against the bulletproof glass.
He swayed his broad tail and sang to her in a sweet, lingering voice like a whale song. A crack appeared beneath the scales on his tail, and its vivid colors seared Qin Yan's eyes.
Qin Yan realized what he was doing. "..." This absolutely cannot be posted.
Through the glass, the mermaid let out a wicked laugh, then lashed his tail against it with a loud bang, making her jump. Under Qin Yan's astonished gaze, he turned and swam into the coral.
Qin Yan deleted the inappropriate content from her camera, then blushingly saved a copy on her smart device.
Late at night, the mermaid sang to her again and again, declaring his love.
Qin Yan had acquired a secret.
She seemed to have fallen for a monster, and one whose sweet, innocent appearance hid a mean personality.
One day, the indescribable Evil God returned. They said he was the monsters' chief deity, come to save his followers.
The Bureau was breached. As the crowd fled, Qin Yan stumbled against the flow of people.
She reached the reservoir and used the last of her strength to open the floodgates. The rushing water washed the blood from her body.
Qin Yan fell to the ground. A curled tentacle squirmed in her sleeve; she had already been parasitized. She had no regrets, as long as she could see the mermaid regain his freedom one last time.
But the mermaid didn't leave. He bent over the dead human and buried his head in her sleeve like a puppy, making a choked, mournful cry.
When Qin Yan woke again, she found herself on an unfamiliar wasteland planet.
Not far away, the mermaid was dragging a blood-soaked star beast toward her.
She reached out to him. Countless curled tentacles poured from her sleeve, wrapped around his waist and tail, and dragged him roughly toward her.
Qin Yan: ?
So...
She had become an Evil God?
[The resilient human heroine, parasitized and then turning the tables on the Evil God × the seductive, pose-loving mermaid hero]
★Reader's Guide★
1. Girl-on-boy romance, one-on-one, both leads have had no other partners, happy ending.
2. Normal anatomy; the heroine has tentacles.
3. Not a strong heroine story. The heroine is an honest, hardworking office drone, and stays true to herself after becoming an Evil God.
