She is part of the Miami City Police and is a lot more calm and aware of things than her partner, Yao. She seems to always be on top of things. Her father is the Chief of the Miami Police. One of her hobbies is wealth management, and sometimes whenever Yao's dad would cut her off, Lu would lend Yao money... but at a high rate of interest. But otherwise, Lu cares about Yao a lot, and although she doesn't show it, often worries about her.
