Jiang Yiqing is an ordinary social creature. He commutes to and from work every day, and his life is very regular. Although he always encounters scenes where the boss of the company quarrels with his young wife - makes up - quarrels - and makes up. When passing through an alley, he can see couples from the school next door having sex. While eating, he can encounter a handsome boy holding a mahogany sword and dancing solemnly in the toilet, and other strange things.
Jiang Yiqing thought these were all harmless annoyances, until one day... A cute new system hit him.
System: You are so awesome. You can guest star in multiple plot lines and still live well. You must be a big shot!
Jiang Yiqing:? ? ?
System: Boss, I just checked your lifespan and found that you will die soon. I think your temperament matches my name very well. Are you interested in binding me to do tasks? Our system bureau is absolutely formal and the salary is generous, blabla...
Jiang Yiqing, who was dying soon, finally bound to the system, and at the same time he also learned the name of the system - the Passerby System.
Jiang Yiqing, who has seen multiple plot lines in this world: ... It really matches him well.
Passerby A and Passerby B are a pair of close friends. They can be passers-by who watch the protagonist's struggle history, or they can be the people who witness the protagonist's love. They never have names. The only ones who can be related are a classmate of the protagonist and a friend of a friend of the protagonist. An introduction when they appear is considered the highlight moment of many passers-by.
Countless passers-by in the Three Thousand Worlds were angry that they had no names in the plot line, so the passer-by system came into being.
