The virus had a latency period of at least two years, after which one needed to take a drug to delay the outbreak of the virus. As long as one did not betray the organization, the virus would not break out.
However, once someone betrayed the organization, there would no longer be an antidote available, and it wouldn't take long for the virus to erupt and cause death.
That virus had no antidote, and the infected would not die immediately but would slowly suffer until death.

Yet her life continued to deplete day by day, and at that time she thought she was surely going to die. She wondered, since she was dying anyway, why not be selfish for once?
So, she made a request to marry Tang Yuchen, hoping to become his wife.
