In 2037, mankind enters the era of "emotional legislation":
If the heartbreak value exceeds 80, you can apply for "memory disconnection", and the state will delete all memories related to a person; if "emotional contraband" appears, those who keep their memories privately will be hunted down by the "Psychic Investigation Team".
Human beings use technology to escape pain, but they also lose the only evidence to prove "I have loved deeply". When pain can be cleared with one click, the weight of love will also be reset to zero.
Concept: "If memory can be deleted, is love still worth remembering with pain?"
