I've Got this Cannon Fodder's Back

I've Got this Cannon Fodder's Back summary:

Lu Zhiguang is not a cannon fodder himself, but his mission is to save the miserable cannon fodder.
A businessman who lost in a business game. A teenager who kept silent under school violence. The actor whose road to fame was ruined by cyber violence. An unknown man who was misunderstood until the day he died.
There can only be one protagonist in every world, so fate hides in the corner sending it’s cold tentacles toward the innocent.
Some people stay silent, some choose to compromise, some are unwilling, and some are fulfilled.
There should always be individuals to hug them.
So Lu Zhiguang went to hug.
Then people will not let go.
