Zombie Sex and Virus Reincarnation

In 2020, a mysterious virus outbreak occurred.

People infected with the virus lose consciousness and attack others one after another.

But the virus lives only inside male semen, which makes it possible to treat the infected by removing their semen. The main character’s boyfriend died during the first wave of the virus, which led her to volunteer to fight the virus. But when she walked into the police station, she didn’t yet know what secrets this virus held.
