Some people swore the house was haunted. The house one weary boy had lived in all his life. What haunted that house was many different entities. A pair of ghosts, always bickering and fighting and too wrapped up in themselves to see what they were doing. They had taken care of him since birth. A girl with a smile so unforgettable and eyes like cobalt, she haunts his home, never leaving his view despite leaving a part of his life. A group of ghosts, from many different areas that he had seen before. Many more fleeting ghosts haunt his life, never leaving. One time, he tried to join them, leaving his body to be just another fleeting figure in someone else’s house.

But it never worked. He could never escape in his eyes. His perpetual purgatory made him realize many things. Maybe things weren’t so bleak for this barmy boy. He was always in his house, but it had many rooms, many people to explore. Schools and malls all with people who he cared for more than himself. One day he invited his friend into his haunted home, despite knowing that if he did that, they’d become another ghost, tormenting him until he could no longer stand it.

He was wrong.

He made friends that helped him through his trying times. He met the people the ghosts were from again, realizing that most of them aren’t the same as his tormentors. The spirits slowly backed off, still always there, but much more unnoticeable. There was only one final ghost the boy had to deal with.

Himself.

What he had done before when he wasn’t pushing it away was fight it. He’d punch and hurt and cut the ghost to make him leave. It never fully worked. This time, he had a new method.
He made peace with himself. He loved and took care of that final ghost. Finally, the spirit had stopped belittling him, and loved him back. Nothing was ever the same again.

This was based on the prompt; The story starts with "Some people say the house was haunted" and ends wuth "Nothing was ever the same again".
