Why does this not feel real?

When Ji Feifei was charged with illegal possession of weapons and jailbreak out of nowhere, she was in disbelief. Both of those were Xia Luna's crimes! How did it end up being on her head instead? How could Xia Luna trick her? 

She didn't know it, but as soon as Xia Luna entered the other room, right before the police arrived, she slipped out of the house through an exit only she knew existed. 

In the past, when Xia Luna was living in the building, she had created a secret passage for emergency purposes. The passage was hidden deep inside, so even if police searched every nook and cranny of the house, it was practically impossible for them to find the secret passage. It directly led to the exit on the opposite side; thus, she was able to escape stealthily.

… 

 On the other side, Li Lanni was relieved when the police informed them that Ji Feifei had been caught again.
