"Bella, she..."

Lisa was waiting for an answer from Rangga with a pounding heart. She was afraid that her sister would do something embarrassing that would ruin her image in her friend's eyes.

"She's just fine! Bella is a fast learner in my opinion. She might be a bit complicated sometimes, you know, she just graduated from college, so her working experience is still lacking. But no problem. So far, her performance is good!"

"Oh god, do you want me to have a heart attack!" Lisa replied, hitting Rangga's shoulder jokingly.

Rangga laughed dryly at Lisa's panic reaction as if she was a drug dealer caught by the police. 

"Thank you very much for taking care of my sister at the office. Hopefully, Bella won't bother your work in the office," Lisa said, sipping her cold latte.
