In 1860 AD, there was a saying circulating in society: "What you lose must be gained."
Su Mingye looked at this sentence and remembered that his lover once said to him: "Don't care about my departure, we will meet eventually. Whatever you lose, you will gain. I will always love you, my night."
There is a rule that cannot be violated in the Changying Laboratory: it is forbidden to have feelings for the experimental subjects. No one has ever violated this rule, because no one knows how vicious the experimental subjects are.
Even Su Mingye himself could not have imagined that he would be the first person to violate this prohibition.
Intention: I write it down as soon as I think of it
