"Yes, Master." Olivia Thatcher instantly replied.
Finn Lewis didn't hide this from Kay Lee. Even though Kay knew about Olivia's existence, she likely didn't know that Olivia could still contact Finn even when her car isn't present.
"It's okay, don't be scared, don't be scared. I will arrange a new assistant for you when I get back, so this kind of thing won't happen again." Finn gently reassured her.
"Um... who is Sarah?" Although Kay was frightened just now, she did see Sarah dispose of those men. Even without any prior exposure to this field, she understood that Sarah was not just an ordinary person.
"She is a secret agent." After some thought, Finn decided not to hide this from Kay. The feelings between Sarah Wood and Kay Lee were probably genuine. While agents are not supposed to harbor emotions, humans inevitably have feelings. Telling her this may distress Kay, but after all, Sarah could be seen as manipulating their feelings.
