After Marking the Villainous Professor

Currently updating: After Getting the Male Lead's Aunt Pregnant

Xu Man transmigrates into a female side character with the same name in an ABO apocalypse novel.

The original character is a rich heiress. Before the apocalypse, she follows the male lead to his university and opens a supermarket to pursue him. After the apocalypse, he sweet-talks her into giving him the supermarket and all her employees. In the end, she dies without a body left behind, a tool who simply delivers equipment to the male lead.

After Xu Man transmigrates, the male lead is cornered by zombies and coaxes her into opening the supermarket doors. "Just open the door and save everyone. I promise I'll be your boyfriend."

Xu Man raises a hand and points at the glamorous, mature woman beside him. "I can open the door. I want her."

No one knows that she's the male lead's unattainable first love, Professor Zhou Yutao, who later becomes the novel's major villain.

Male lead: "...No."

The others look furious. "Right, we can't sacrifice Professor Zhou."

But Zhou Yutao smiles. "It's fine, as long as everyone survives."

Xu Man thought she had it all figured out, but somehow things went wrong.

That night, Zhou Yutao corners her against the wall. "I hope you mean what you said. After this, leave my students alone."

Xu Man is horrified.

No, no, no. That's not what she meant. She just wanted to stay by the villain's side and scrape by with her life.

A new supermarket opens at the school, run by a beautiful young female alpha. Zhou Yutao likes her a lot. Whenever she has a moment, she goes there to buy a bottle of water, just to see her.

But it doesn't take long for Zhou Yutao to realize that this alpha is there for someone else.

She's upset, but there's nothing she can do.

Then the apocalypse hits, and she and a group of students flee to the supermarket. To her surprise, the alpha singles her out.

Good. If she's with her, then she won't want anyone else.

No extra organs, with some original worldbuilding.
