There is a group of "memory repairmen" in the world who do not delete memories or tamper with life, but only prune "deteriorated memories". People will twist originally ordinary memories into shackles because of obsession, regret, and sadness: For example, thinking about the death of a loved one as one's own fault, twisting a friend's goodwill into malice, and magnifying regrets to trap them for life. People cannot have their memories tampered with, but they can distort their memories themselves. Regret will magnify small things, grievances will misinterpret the kindness of others, and obsession will trap you for a lifetime.
