Father Yu and Father Yuan are enemies.
Why are they said to be enemies? When they were young, they were doing business together. Who knew that Yu's father stabbed Yuan's father in the back, causing him to almost go bankrupt. Of course, Yu's father didn't end well in the end. Yuan's father cooperated with others, leaving Yu's father in ruins.
Father Yu said that he and the Yuan family were sworn in.
Yuan En has always known about the entanglement, and the relationship between him and Yu Ji is not much better.
