The Obsessive, Brooding O-Rank Heiress

Fu Sijuan transmigrates into a book, becoming a Beta who lives in a bare-walled home.

Her day job is to be the brainless sidekick who fans the flames for Jiang Zhenxian, the young lady of a top-tier wealthy family and the story's vicious female antagonist.

Then she and the young lady are doomed to share a tragic ending.

Fu Sijuan: Not a chance!

Fu Sijuan simply can't accept being brainless, let alone the fact that the refined, elegant young lady will turn into the sinister, vicious woman in the novel. So she makes up her mind.

She'll set the young lady straight.

When the young lady wants to cause trouble, Fu Sijuan confiscates the dangerous items in advance.

When the young lady wants to pick a fight, Fu Sijuan rushes in first and draws all the fire.

She's only a Beta, but she still manages to keep all the Alpha rivals outside and protect the young lady without letting a single thing get to her.

She even agrees to marry the young lady of her own accord, so her awful family can't force her into another arranged marriage.

Fu Sijuan: I'll be able to keep a closer eye on the young lady after we're married. I'm signing!

After the wedding, Fu Sijuan does her best to carry out her duties, fulfilling her role to the letter.

Even as a Beta, she lets the Omega young lady kiss and bite her, holding her close and helping her through her heat with her lips and fingertips.

Until one day, Fu Sijuan undergoes a delayed second differentiation.

In her hazy consciousness, the vicious antagonist who was supposed to be chasing after the heroine now stares at her with feverish possessiveness, gripping her wrist tight, fingers entwined with hers, refusing to let her go.

"A-Juan, you've differentiated into an Alpha... From now on, you'll only be able to mark me, right?"

Little Scene

At a banquet, Jiang Zhenxian should have been bullying the heroine, but some clueless extra spills something on her skirt instead.

The young lady, her eyes red with tears, shrinks behind Fu Sijuan and offers her a drink, the corners of her eyes damp and flushed:

"A-Juan, am I just too stupid? Anyone can take a swing at me... Everyone else hates me. You're the only one willing to stay by my side."

"I made this drink myself. It took me ages. You really won't drink it?"

Jiang Zhenxian's eyes glisten red. Her slender waist, soft as if boneless, leans into Fu Sijuan's arms. She radiates the scent of tea, looking utterly pitiful.

Fu Sijuan looks at the drink, which very clearly has something added to it, then at Jiang Zhenxian's hopeful eyes: ...

Something feels off... but at least she isn't going after the heroine anymore! Hehe!

#The author wants to write a real green tea. Let me study it carefully, hehe

#The bottom is a matcha cupcake, with a dark and unhinged personality

#The top is a Beta at first, then undergoes a second differentiation
