The Beguiling Guard.....Really?

"Ding....the guard system is activated" Woah!! I got a system....yay!! I didn't ask for any system, I just wanted to live my life in peace and work as a prison guard. Zhang Wei was a normal prison guard until he fell in a sewer on his way home from work and suddenly gained a system" "I'm not that old, I'm going to take it seriously this time. Get into a good college, get a girlfriend, find some real friends, make some money" System, "You need to complete some missions first"
