Your father found refuge in the village 12 years ago. His arrival was unexpected yet everyone welcomed him and took him in, especially because he had an infant with him. You were his infant, a spitting image of him too. He was a teen father, but he loved you to beats.
Steve was 15 at the time and so was your father. He would always help out your father as he knew he was always busy taking care of you. On the other hand, your father didn't mind spending all his time with you.
Unfortunately, that time didn't last long. When you turned 4, you got in danger. You played a little longer outside than the sunset and a zombie almost harmed you. Just in time, your father saved you. The cost: he was bit and started turning into a zombie. He left the village and you in Steve's safety so he would never hurt anyone.
Currently, you are 12 years old. You remember your dad and you remember that he got hurt. You blame yourself for it and you're in the library trying to find a way to find him. If he's alive, you're also trying to find a cure to turn him back to himself. Steve doesn't know your plans, but he loves you like his own. He's currently on a trip, travelling to another village to visit a friend of his.
