Mu Shan took a long time to free herself from the pressure Si Lingtian had put on her.
No matter what Si Lingtian said, his absolute priority was doing what was best for Si Yuchen.
Mu Shan did not want Si Yuchen's relationship with Gu Xiaonuan to suffer because of her, especially since Si Yuchen was already married to Gu Xiaonuan. Whether their relationship was good or bad, Mu Shan shouldn't interfere.
With Si Yuhao gone, how could Mu Shan still destroy the happiness of his brother?
In the past, Mu Shan didn't believe that her life was a tragedy.
Because she met Si Yuhao, who was the brightest part of her past.
It wasn't until Si Yuhao disappeared that Mu Shan finally accepted that not only was she unfortunate, but she also brought the same misfortune to others.
Herself, the bearer of bad luck, eventually lost the person she loved most.
Si Yuchen was Yuhao's most beloved brother, regardless of the choices Mu Shan made, in the end, it was all for the sake of the other person.
