After Our Marriage Alliance, the Scum Alpha Went Straight

Original title: Married Off to My Ex-Girlfriend

He Yaoyao had always moved through a crowd of admirers without letting anyone get close.

Except for one unexpected mishap...

Three months ago, He Yaoyao dumped her poor girlfriend, Meng Li, with the excuse that she couldn't repay her debts, and cut things off cleanly.

A friend who'd helped her pretend to be poor brought her some news:

Meng Li was now with a rich old man.

He Yaoyao felt a pang of regret as she remembered how beautiful her girlfriend was.

Her friend unzipped her backpack. "Meng Li gave this to you."

He Yaoyao: !!!

This is money from selling herself (._.)

Three months passed, and there was still no word from her ex-girlfriend.

He Yaoyao was dragged along to a wealthy family's banquet.

Then

she saw her dazzling ex-girlfriend.

He Yaoyao: !!!

Should I run or play along?

Note:

He Yaoyao is an alpha | Meng Li is an omega

Female alphas have no organs; they attract others through pheromones only
