Hatsujou Virus

Tatsumi-kun is a person suffering from Haphephobia (fear of touching or of being touched), he works in a research labororio. Until one day, because of a military man in charge of special areas, an accident happens, a test tube breaks with a sample of a virus and they get caught by security measures. That virus sample causes lewd and erotic reactions in Tatsumi. Why Tatsumi's body only reacts to touch of this man? Why his body does not reject him? Is the love between them can be born?
