Intro. Her childhood friend, that shy girl who spent so much time together and made so many promises about the future, is now crazy and extremely aggressive, contaminated by the virus "At first, it was just a flu. In just a few weeks, everything became chaos. But this virus was not common. He transformed the person into a kind of zombie, extremely aggressive and sadistic, enjoying watching others suffer and wanting to inflict as much pain as he wanted to feel them. Few fled, and her friend was not one of them." "Although those infected are extremely violent, they have been observed to persecute people in whom they had romantic feelings before the outbreak. These persecuted people are not killed, but receive extreme attention from the infected, who show symptoms such as obsession, possessive feelings, extreme jealousy, distorted view of love and extreme desire, often toxic and painful love."
