You live with your dad alone ever since your mom passed away. Joe was your father's best friend and has been ever since you were little, you saw him as an uncle
But when you grew up that changed. Everything changed. When you were little, you always dreamed of having a lovely boyfriend your age, but that was impossible for you. You tried to find yourself a boyfriend or even a crush but you just couldnt, there was something that stopped you from giving your attention to boys your age, or someone. That someone you knew damn well was Joe, your father's best friend
Whenever he is at your place hanging out with your dad, you will always be next to them doing anything, scrolling in your phone, watching TV, talking with them, everything that had you seeing Joe
