Can you recommend some anime or novels about the love story between a two-faced man and a soft girl or between a soft man and a two-faced girl?

I'm not sure specifically which 'two faced man story' you are referring to. It could be about a man who shows two different personalities or sides, perhaps one that is good in public and another that is bad in private.

"The Unscrupulous Concubine's Daughter" is a novel that meets your needs. There is a pair of black-bellied male and female protagonists in the story, and their battle of wits and courage is very exciting. I hope you like my recommendation. Muah ~

Yes, I recommend the two novels,"The Cute Wife Haunts: Don't Make Trouble, Master" and "The Love of a Married Man, Doting on His Wife Without Limits." They were all modern romance novels about wealthy families. There were also black-bellied male protagonists, but the plot and character settings were different. It was worth reading. I hope you like this fairy's recommendation. Muah ~😗

If in the 'two faced man story', the man is in a community. He might publicly support a new building project, saying it will benefit everyone. But privately, he is against it because it might reduce the value of his own property.

He could recommend "Married Heart As Before: The CEO Is Too Good at Flirting His Wife." It was about a girl from a humble background who met a black-bellied CEO and signed a contract with him, starting a period of being at his mercy. Six years later, the girl returned with her black-bellied son. Could she finally get back her happiness? I hope you like this fairy's recommendation. Muah ~😗

I recommend My Bully President. The relationships and interactions between the characters are very exciting. The plot is full of ups and downs. It's very worth watching. At the same time, it was suggested to follow the author to see if he had any other works related to marriage, or to ask for other readers 'recommendations in the book review section.

I recommend the following novels to you: "Genius Baby's Black-bellied Daddy Bullies Mommy,""A Paper Marriage: Genius Baby's Black-bellied Daddy," and "Cute Baby Attacks: CEO Daddy Is Too Hot." These novels all have elements of genius babies and black-bellied fathers. You can give it a try. I hope you like this fairy's recommendation. Muah ~😗

I recommend Fatal Favor: Ex-Husband, Hug! Here you go. In this modern romance novel, the male protagonist is a two-faced, black-bellied, cold, and aloof character, while the female protagonist is a love-struck daughter who can be sweet and valiant. Their marriage came to an end because the male protagonist filed a divorce agreement. After the divorce, the female protagonist began to work hard to get rich, while the male protagonist regretted it and began to pursue the female protagonist. The story was full of sweet and happy scenes. I hope you like my recommendation, Mwah~

I recommend " Evil Emperor and Demon Empress: The Best Black-bellied Alchemist " and " Venomous Steps: The Genius Black-bellied Fiendish God " to you. These two novels are both ancient romance novels. The protagonists are both black-bellied women. The plot is unique and the development is complicated. It's very good.😋I hope you like my recommendation.😗
