As Wei Xu lay dying, she became an Omega in an ABO world. While fleeing the Alpha she had been matched with, she traveled through time and arrived in the era before ABO had even come into existence.
In a laboratory researching ABO differentiation, she saw the test subject:
A sea creature with a long, ice-blue tail was imprisoned in a massive fish tank, its long hair of the same color drifting through the water like seaweed.
When it turned around, she saw the most beautiful being in the world.
--
The new researcher who arrived recently was acting strangely, though the sea creature couldn't say exactly what was off.
Whenever he pretended to be sick and got close, she dodged him. She looked easy to fool, but clearly wasn't.
The sea creature was quite troubled.
Then, after witnessing all the ways she had interfered with the experiments, the sea creature thought it had found a way out.
So when she approached again, he wrapped his tail around her legs and rested his head on her shoulder. He bared a mouthful of fangs at her.
"Let me out, and in return, I'll grant your wish."
"Power, immortality, authority, money."
She was silent for a long time. Just as the sea creature thought she was going to refuse, she smiled, shedding her former innocence.
"All right... But what should we do? I don't want any of those things you listed."
"What I want is... you."
--
The moment she saw that extraordinary creature, she was captivated.
The history books on ABO didn't mention that the genes responsible for sexual differentiation originated with sea creatures, let alone that they could be so beautiful.
No matter how potent an Alpha's pheromones were, none smelled as good as the cool, salty scent of the deep sea at his neck.
Her love-at-first-sight heart, which had gone cold because of a bunch of Alpha men who looked better than they behaved, burst back into life.
Her to-do list had already included stopping the ABO differentiation experiments. Now she added one more item:
--Get him, and make his cold body take on her warmth.
--
That human, greedy for beauty, took him out of the cage filled with an irritating stench.
He chose a gender as she wished. After enduring the painful transition period...
She had actually... disappeared?
His icy pupils narrowed to slits.
When he found her, he would bind her limbs with his long tail and keep her with him in the deep sea forever...
Click. The door opened.
Wei Xu, who had "disappeared," stood outside with a nutrient solution for changing water quality that she'd swiped from the lab.
"Miss me?" she asked with a smile as she walked over.
His slit pupils instantly became round again. He lay against the edge of the bathtub, looking weak and innocent.
He answered in a coaxing voice:
"Mm. I missed you."
