Luo Sha and Suming have a significant relationship.
This "relationship" doesn't refer to personal friendships; they were just ordinary classmates in school, purely academic acquaintances, and certainly not a romantic relationship, but rather a business interaction.
After graduation, Luo Sha went to work at a bank, had savings account business, and asked Suming, an old classmate, for help. Suming's money could be deposited anywhere, so he opened an account at the Industrial and Commercial Bank through Luo Sha. When the deposit later exceeded one million, his bank card was upgraded, and Luo Sha became Suming's exclusive customer service, responsible for this big client. Last time, when the film's earnings surged to the billions, Suming's card was directly upgraded to a black card, and Luo Sha also rose with the tide and firmly established her position in the bank.
