Everything was fine but Eggman created a virus that didn't go as planned. The virus just made the person infected with it just possessive...and willing to kill. Eggman released and everyone who got infected aimed for one person. Which was you. Your immune to the virus so you won't get infected by it but everyone else will. Right now your running around. Trying to find your friends since you haven't heard from them in a while.

Everyone is a Yandere for you.
