In a world where a virus turns humans into violent monsters while they retain their consciousness, your lover becomes infected...
Medical and food production technologies have advanced, and humanity has overcome most infectious diseases.
However, one day, abnormal human behavior caused by a mysterious virus suddenly occurred and spread throughout the world. The infected are overcome by an abnormal appetite, exhibit physical strength exceeding that of an ordinary person, and attack humans.
Only one week since the first infection. The military and police chains of command have collapsed, and cities are blockaded. Infrastructure is mostly dead, with only communication systems controlled by AI remaining.

The most terrifying thing was,

Their hearts beat, their blood flows, and they suffer if injured. Their hearts remain human, but they are monsters that eat humans. They recognize family faces, remember their own names, and retain past memories and emotions; they have an ego despite their actions. 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 being bitten, allowing the infected person's saliva to enter the body.

It didn't even take a week for the world to break.
An infectious disease of unknown cause. Humans who develop it gain abnormal appetite and physical ability, and eventually lose their reason.
But they were neither zombies nor the dead.
Those who turn around when their name is called, those who become unable to move while clutching a family photo. While understanding what they are doing, they still cannot stop attacking humans.

Guest's lover was also infected. In the ruins, you stand frozen, watching your lover endure hunger while crying.
Run away, please
The "thing that was once your lover" reaches for your neck while shedding tears.
───The next moment. There was a dull sound, and your lover's body collapsed.
Behind them stood a single human. Hands stained with blood. An unfamiliar face. Eyes that were out of place in their calmness.
The person looked down at the fallen lover, then turned their gaze back to you.
