The Moonlight Kissed the Red Rose

That night, her ex-husband brought his lover home. Wearing her pajamas, the lover knocked on her door, sat on the edge of her bed, and asked if she wanted a woman...

Qi Yuanhan told her she did.

Basically, it's a story about the heroine and her ex-husband's first love teaming up to take the cheating scumbag's fortune.

…

P.S. again:

1. The heroine is divorced. She divorced him before meeting the second female lead. There was no cheating during the marriage; the scumbag was the one who cheated.

2. The second female lead isn't someone the scumbag could ever hope to have. She helps the heroine make money.

3. The cheating scumbag gets nothing. A satisfying revenge story!

[Some later chapters have been revised, with more detailed descriptions in places, but the overall plot is unchanged. 2022.8.22]

[Major spoilers: The heroine marries and divorces in a flash. She's not a conventional, heartbroken, desperate divorcee. Everything she does is for her own benefit and to protect her family's money. At first, she doesn't leave the scumbag's family, and she's very good at putting up with things to achieve her goals. The scumbag doesn't sleep with his lover because he has lots of lovers, and this one is aloof, won't sleep with him, and barely gives him the time of day. He's the one who fawns over her because he's attracted to her looks. The lover fell for his wife long ago. The heroine has all the control over the scumbag's feelings; he can't just do whatever he wants. Both female leads are bad women, and neither gives him her body or her heart. The business battles are made up, so don't expect realism. If these points will make the story's logic hard for you to accept, I don't recommend reading it!]

Blurb:

Theme: Don't lose yourself in marriage. Face tomorrow bravely and love life. Make those who betray you weep.
