My Junk Repair Shop Only Repairs Life's Regrets

In a quiet corner of this hustle and bustle city, there is a junk repair shop that never closes. The rules in the store are very strange: don't ask about the origin, don't ask about the past, only practice "regrets in life". Lu Shi, the young man who inherited the store, had a pair of eyes that could see "causal cracks." With a pair of skillful hands, he can repair far more than just the defects in the objects. A stopped pocket watch, behind it is the love of a century that was missed for a century during the war; A broken string brings out the heavy heart of a talented musician betraying his best friend; A cracked trophy carries the clumsy love that a strict father never expressed. Lu Shi wandered in the light and shadow of other people's memories, mending the scars that tore apart time and space, and received "a happy memory" as reward. He thought he would always be the calm bystander until... When business giants hold billions of wealth in their hands, just to ask for repair of regrets that are "not cruel enough"; When the mysterious "Recycler" emerges from the shadows, eager to devour the most extreme pain as food; When he discovered that the biggest regret deep in his heart was actually a carefully planned conspiracy—— Only then did he realize that what he was repairing was other people's past; but what needed redemption was his own future. ——Welcome to [Guangyin Grocery Store].
