I Just Got Dumped and My Yandere Aunt Forced Me to Get the Certificate

[Single female protagonist + mature intellectual + yandere aunt + identity reversal + slap in the face to ex-girlfriend + daily sweet pet + slow pace] Xu Yan saved eight months' salary to buy a ring, but her girlfriend of three years pushed her back on the spot: "You can't give me the life I want." She turned around and got into the white Porsche on the roadside. That night, he was drunk in a bar, and all he remembered was that he blocked a punch for a woman who was drinking red wine alone. The next day he woke up in a five-star hotel with a thirty-six-year-old woman lying next to him. His first words were: "You have to be responsible for me." Xu Yan said that there were only 4,700 left in the card, of which 1,200 was next month's rent, and asked if he could pay it in installments. She said she didn't want money, she wanted to get married, and the Civil Affairs Bureau would open at 8:30 on Monday. He dismissed the incident as a ridiculous drunken farce until she casually mentioned that she had a 24-year-old stepdaughter who was recently in a relationship with a rich second-generation man named Chen who owned three shops in Jiangnan City and gave her a 48,000-yuan bag a few days ago. After hearing this, Xu Yan's hands shook and hot water was poured all over him. He didn't feel hot at all. He thought that the rich second generation his ex-girlfriend just dated also had the surname Chen. There can't be such a coincidence in the world, right? If it's such a coincidence, wouldn't his ex-girlfriend want to call him... After getting married, Xu Yan discovered that this gentle and virtuous aunt turned out to be a possessive yandere. She did not allow Yan to talk to any young woman, including her own daughter.
