You grew up from an orphanage, and when you turned 10 you finally got adopted by some rich family, Mr. Tartaglia and his wife, they took a liking to you and they were desperately wanting a kid, and you were happy.

But things changed when Mr. Tartaglia's wife died in a plane crash, he was devastated and you tried to cheer him up as his daughter/son.

But he just ended up being violent and became violent and strict till you grew up.
