My Beta Fiancé Is a Tentacled Demon Lord [ABO]

(Mary Sue, adored by everyone, with a battle royale of male suitors)

Yin Hua transmigrates into a dating sim set in an interstellar ABO universe, becoming the evil supporting character who shares her name.

This character is the crown prince’s fiancée: a gorgeous, wicked-hearted, spoiled young Omega lady.

She repeatedly targets the sweet, innocent heroine and nearly kills her. In the end, she gets what she deserves: thrown into a horde of aliens and devoured by monsters.

Yin Hua: ...I have to admit, this is a classic plot, but the villainess gets such a horrible death!

After transmigrating, Yin Hua tries to escape the plot so she won’t die so horribly. Her first step toward success is finding herself a new fiancé.

Her new fiancé is an utterly ordinary Beta. Apart from being handsome, he’s mediocre in every other way, which makes him feel incredibly safe.

Yin Hua’s eyes gleam as she holds her Beta fiancé’s hand. "A Wei, I’m so glad we got engaged."

The Beta fiancé tilts his head, then curls his lips into a smile. "Me too."

Beneath his ash-gray shirt, sticky, winding tentacles stir restlessly, struggling to wrap around the girl’s waist.

He murmurs softly, "I love you."

In the interstellar age, humanity’s conquest of the universe is halted by repulsive, twisted monsters known as "aliens."

The most dangerous of them all, the one at the very top of the alien hierarchy, is also the most savage and greedy.

In the past, people called it "Taotie."

Now his name is He Zhiwei. He’s a Beta who can’t smell pheromones, and he has an Omega fiancée who ranks among the empire’s very best.

He wants so badly to swallow her whole, yet he can’t bear to eat her.

All he can do is keep her by his side, smelling her again and again.

Humans don’t know that, besides pheromones, his fiancée has so many other wonderful scents.

But so many people like his fiancée, and that makes He Zhiwei feel irritable.

Don’t you people have fiancées of your own?!

I really want to kill them all.
