(Y/n) Graves / (N/n) Bio/ Background Information

Disclaimer: Namlei is the developer of the Game/(Franchise?) of The Coffin of Andy and Leyley. I just had an idea of making this story that's it, but this entire story won't be a complete reflection or carbon copy of the game. (Y/n or N/n) is the adopted by the mother and father of Ashley, he's one year younger than the sister. Don't expect (Y/n) to be a replica of Andrew, he's going to be a replacement for Andrew, but he won't act like him. This is going toto be an Alternate Universe where Andrew was never born. Everyone in the family knows (Y/n) is adopted except for him, he thinks he's there biological son.
