At Two O'clock in the Morning, My Brother-In-Law Secretly Gave Me a Red

Late at night, my sister-in-law Lin Nian felt a red envelope under her pillow. The cover said: "Happy birthday, don't tell your sister." Inside was two thousand dollars. She recognized it as her brother-in-law's handwriting. The brother-in-law explained that it was private money and he did not dare to let his sister know about it. Lin Nian believed it and hid it for him. It wasn't until she accidentally turned to her sister's cell phone that she discovered that the whole thing was a carefully designed test - her sister was testing whether she would have an affair with her brother-in-law. What she didn't expect was that there was a dispute over the inheritance of an old house and a shocking secret about her mother. A red envelope reveals the calculations, misunderstandings and protections between three generations. When all the truth comes out, who is the worst person? Can family love withstand the test? Reversal and reversal, waiting for your comment.
