Just like my name, second side, the heroine of the story is a person with two sides. Even she doesn't know who she is, and even others don't know. This story will use the identity of the heroine as the first clue, that is, the bright line, and at the same time use a huge conspiracy as the dark line to slowly unfold, and this conspiracy is closely related to curing diseases and saving people. However, this is still a light-hearted article. The heroine and the hero will be happy. (The chapters without titles are duplicates, I modified the structure)
