From her observations during this period, she felt that Long Feiting was a person who would overlook other people's shortcomings. Even if he didn't like Mu Kexin, he would not allow anyone to bully his benefactor. If Mu Kexin launched any attack on Mu Huan, Mu Huan wouldn't let the girl off for sure. This way, Long Feiting wouldn't let Mu Huan off as well!
At that point, all she needed to do was to sit back and watch Mu Huan fall into dire straits!
"I just need to stop being scared of Mu Huan, why should I need to create trouble for her and suppress her?" Mu Kexin felt that even if she didn't need to fear Mu Huan exposing her, she should still avoid her, not create trouble for her!
