If Katrina isn't mistaken, Sophie is currently so frustrated and angry with her that she wants to kill her at any moment.
Given this, Sophie can't be calling with good intentions.
But she can't possibly be calling just to hurl insults at her, can she?
While Katrina ponders on Sophie's purpose, Farrah reaches out and picks up the phone. "Katrina, since you're unwilling to pick up, let me answer it for you!"
Farrah's eyes flash a hint of resentment. She wants to kill Sophie's spirit, so she doesn't dare behave arrogantly or bully Katrina in the future again.
Katrina knows that Farrah must want to take the opportunity to teach Sophie a lesson. But she doesn't want to involve Farrah in her troubles with Sophie.
After all, Sophie has no shortage of hatred. It can't be good if she sets her sights on Farrah.
Katrina hurriedly takes the phone from Farrah's hand. "That's all right, Farrah. I can answer it myself. She can't bully me again."
