Mu Yangling was right—there was indeed a rift between Mu Shi and Mu Bowen. Otherwise, Mu Bowen would not have looked for Mu Yangling, hoping that his sister would be able to mediate the conflict between the father and son.
However, Mu Shi's letter directly extinguished Mu Bowen's enthusiasm.
In the letter, Mu Shi reprimanded Mu Bowen for not being considerate of his older sister. Since she had married into the royal family, she had to be careful with her words and actions, and she must have a lot to do. It was not easy for Mu Yangling to make a trip back, so he shouldn't let her fret over his matters.
He warned him not to tell Mu Yangling about this.
Mu Bowen could not help but feel sad. He could not tell his mother about this, and it wasn't ideal for his younger siblings to interfere. If Mu Yangling did not mediate, would he and his father continue to be in a deadlock?
