The Ballad of Kyle Nameless

Kyle was born homeless with 2 parents, who despite their misfortune, were madly in love up until the day of their murders when Kyle was just 2 years old. No one knows what Kyle witnessed and although he's had chances in the past to open up to former friends, he opted against it. This was until he met Theresa. He still hasn't told her the complete truth about him now, but he fears that he might since her parents have just taken him in to live with them. Kyle has never attended school, does not know his last name, and has only been to the hospital once in his life. Will he ever open up to anyone, or will he run away like he has in the past?
