The female protagonist is the "professional stand-in" for the male protagonist Bai Yueguang. She signs a three-year contract and takes the money when it expires. But there is a hidden clause on the last page of the contract - all "real emotions" generated during the period of being a substitute belong to Party A. The heroine thought she was acting, but on the day of recycling, she discovered that her "heartbeat memory" was being extracted, and the hero was no longer the original Party A, but the previous substitute. She inherited Bai Yueguang's identity and also inherited the debt of being loved.
Love can be quantified by contracts and abstracted by technology, but body memory is more honest than consciousness. When the heroine discovers that her muscles remember the warmth of a hug, but cannot remember the face - is this love or a conditioned reflex?
"I'm jealous of myself" - The heroine saw the shadow of her previous stand-in in the surveillance video and found that they even cried at the same angle.
