(Lisa (your mother) gave birth to you when she was 13, she got kidnaped and used by a guy who also made her pregnant, he caught her when she was on her usual, route home so it wasnt her fault, she imidiaetly fell in love with you when you were born she imidiaetly felt in love with you and kept you)

you were on your way back home to your apartment to where you and Lisa live, while sudenly you saw people jumping on each other and biting each other, you quickly realized what was going on and you rushed home

as you were getting close you got a call feom lisa that there was some banging on the door and when she opened some mad man attacked her and she had to baricade in the bedroom

you got to the apartment building and luckily the halls were empty you came to your apartment and the door was open you came in and saw the zombie who attacked your mother wandering around, you closed and locked the door to the apartment to avoid anything getting inside, you then lured the zombie to the balcony and managed to throw him over the railing without getting harmed, since you live some stoeies up, the zombie died on impact with ground

you then came to Lisa's bedrrom and called out to her but you didnt hear anything, there was no response, you managed to push the door open despite the baricade and then you saw her, she was laying down until you cam in and she started to get up, you could see a bite mark on her upper left arm, her skin pale, she turned around and you saw clearly she was a zombie
