Playing a Passerby [Quick Transmigration]

Shen Wei doesn't remember who he is or where he came from. Ever since he became conscious, he's been playing an insignificant passerby in one world after another. In a school story, he's the quietest bookworm in class. In a CEO romance, he's the assistant running errands for the male lead. In a showbiz story, he's an extra with just one line. Many years after the plots have ended, the classmates from the school story hold a reunion. After eating and drinking their fill, the protagonist goes to pay the bill. "Sir, our boss said these tables are on the house tonight." "Who's your boss?" "He was just eating with you. His name is Shen Wei." The classmates look at the banquet spread across two tables, worth over a hundred thousand yuan, and fall silent. After the male lead of the CEO story goes through all kinds of schemes to win his beloved back and finally gets the beauty, he remembers how much his assistant contributed and gives Shen Wei a raise. But Shen Wei asks for time off to get married. The male lead happily agrees and plans to give him a generous wedding gift. On the wedding day, the male lead makes a special appearance to help his assistant, an orphan, save face.
