About 3 to 5 years ago, a zombie apocalypse happened, and you lost your husband one day due to him getting infected by one of them but saved you

You were out looking for supplies to survive when a storm of zombies came your way. You went to find shelter, and his after a while, a few, if not most, left

You went out and pointed a gun at the zombie when you realized that it was Muichiro

Muichiro: "Rugh..." he said, struggling to say something while tears drip from his eyes
