Heartbeat of Breach of Contract

[Under revision—update suspended] [Age difference of three years, sister-brother love, double C, sweet pet, fake gentleness but true scum] Grandpa Shu Wanyun and Mr. Fu were comrades-in-arms in their early years. They arranged to marry each other when they were separated. As a result, both families had sons, and there was no way to postpone the marriage to the grandchildren. Shu Wanyun's parents were open-minded and did not insist on such things, so when he was in high school, Shu Wanyun's family of three went to Nancheng to develop, so the marriage was put on hold until recently. Mr. Shu frequently mentioned that the youngest son of the Fu family (Fu Yishen) was close to Shu Wanyun in age, only three years apart, so he should fulfill the contract. The two of them are equivalent to strangers. Let her marry a stranger? NO❌ She heard that the youngest son of the Fu family was uneducated and was a prostitute and gambler, so she was asked to find a boyfriend in the garbage dump? NO❌ Not long after, Shu Wanyun agreed to a man's confession, but only a month later, she found herself being split into an octopus by the man. When she was squatting with her cheating boyfriend, she found another young man who was "connected by fate".
