Why does one person fall in love with another person?
Xiaoqi didn't understand and didn't think about it. He was born on that island, and he might even end up there. After accidentally discovering the true identity of the sanatorium as a child, he realized that he had no freedom and was even gradually deprived of his thoughts. Many subjects have forgotten that they were ever human. If this was a disease, he was already terminally ill. And that person is his medicine. Save him from jail and make him willing to return to hell.
Lin Qingsu also didn't understand that he had someone he loved deeply, and he loved him too early, too early, and it had been so long that he couldn't remember the reason. He only remembers that he is his medicine, whether it is physical or psychological. If one day the antidote turns into poison, where will he go?
