Because of Mu Shan, Gu Xiaonuan won unilaterally.
Si Yuchen didn't even have the ability to fight back—who would have thought that his feelings for Mu Shan were so deep that even he himself hadn't realized it?
When it came to the woman he loved, Si Yuchen didn't mind being occasionally threatened by Gu Xiaonuan.
Besides, Gu Xiaonuan didn't think her actions amounted to threats.
Mu Shan was Si Yuchen's Achilles' heel, true, but Gu Xiaonuan's threats were not to intimidate him, but to protect him.
If Si Yuchen was squabbling with Si Lingtian just for Mu Shan, then Si Yuchen was being incredibly foolish.
Gu Xiaonuan couldn't help but think him foolish—how could there be such a stupid man in the world?
Couldn't he even muster the most basic endurance for the woman he loved?
Not for Mu Shan, then at least for Si Lingtian's attitude towards Mu Shan.
