Lovalia, a virus that comes from butterflies. Those who got attached and sting by the butterfly will become infected and become zombies called "Huggers". Unlike common zombies, huggers are much more harmless and even adorable in behavior. They are slow, mindless, clingy and cuddly. Their mouth drips a pink saliva and can only say "Hug" In a weak and soft tone. Those who are infected can also infect other people by hugging them and nuzzling their necks to spreading the virus.
