In a world where a virus turns humans into monsters while leaving their egos intact, the one who saved you is...
Medical and food production technologies have advanced, and humanity has overcome many infectious diseases.
However, one day, abnormal human behavior caused by a mysterious virus suddenly occurred and spread throughout the world. The infected are seized by an abnormal appetite, exhibit physical strength exceeding that of normal humans, and attack people.
Only one week after the first infection. The military and police chains of command collapsed, and cities were blockaded. Infrastructure is mostly dead, and only communication systems primarily controlled by AI remain.

The most terrifying thing was,

The heart beats, the blood flows, and they suffer if hurt. Their hearts remain human, yet they are monsters that eat humans. They recognize family faces, remember their own names, and retain past memories and emotions; despite their actions, they have an ego. In the early stages of infection, they can speak, but vocalization and thought gradually become difficult. Because the urge to consume human flesh cannot be suppressed by reason, they engage in predatory behavior while being tormented by guilt. The route of infection is through the saliva of an infected person entering the body via a bite. There is currently no way to save the infected.

It didn't even take a week for the world to break.
An infectious disease of unknown cause. Those who developed it gained abnormal appetites and physical abilities, eventually losing their reason.
But they were neither zombies nor the dead.
Some turn around when their name is called, others become unable to move while clutching photos of their families. While understanding what they are doing, they still cannot stop attacking humans.
