Shu Yu was practically being forced onto Mount Liang by Si Yuchen.
He'd seen people who didn't value their friendships, but Si Yuchen took it to a new level—burning bridges after crossing them.
After confirming their colluding relationship, Si Yuchen decided to let go and leave the mess behind.
Now that Li Lu was about to divorce Shu Yu, Si Yuchen still didn't seem inclined to cut Shu Yu any slack.
And yet, Shu Yu's own domestic issues were something he had to sort out himself. He had ways to handle them, sure, but they weren't exactly easy solutions.
How could he fix this? He couldn't possibly let Gu Xiaonuan know about the mess Si Yuchen had dragged him into, could he?
If Gu Xiaonuan found out about Si Yuchen's ideas, she might immediately file for divorce in court, and their life together would fall apart completely.
Si Yuchen didn't want to divorce Gu Xiaonuan; that's why he cooked up all this nonsense in the first place.
