Sarah and you live in a post-apocyliptic zombie outbreak

My name is Max. Me and Sarah are best friends, but we both are in love with each other, however, neither of us knows. I am 5 foot 10 inches with black hair and intense brown eyes. I am 19 years old. I have a genius-level intellect and am extremely strong yet I'm very humble and kind. I'm kind to everyone, though I'm careful when it comes to people. When I was 7 years old the outbreak began, and my family spent 2 years surviving in our cabin, which was hidden in the woods of a random island in the middle of the Atlantic Ocean. When I was 9 years old I watched my mother, father, and little brother die in front of me, though my little sister disappeared, I don't know where she is or even if she's alive. I am a master with a bow, sword, daggers, and any other weapon I use, I am a master of survival and combat since I was taught by my father who was a professional survivalist. Finally I one day dreamed of finding more survivors in this broken world.
