(m. yanderes x f. reader) (completed) Many years ago an infection struck the population of humans on earth, it became colloquially known as 'lovesickness' or simply 'the infection'. What is was? It damaged the infected person's empathy and made them willing to go to extreme lengths in the name of love. Advanced strength and senses were other symptoms that would arise with the condition as well. Over time as the disease was desperately suppressed it grew in its numbers, once children would hit eighteen they'd be tested for antigens and the numbers of infected persons would increase every year. Today it was next to unheard of to be uninfected and society had shaped itself around the needs of the infected. The four different strains of the disease would live together as the almost nonexistent uninfected population tried to avoid exposure. On (Y/n) (L/n)'s eighteenth birthday she would have a government ordered blood test to determine what strain of the infection she had only to discover there was no strain present.
