He made his heart flame resistant, so no fire could march in and set it ablaze. It seemed like the perfect strategy to keep the unwanted out.

No Love, no joy, just sadness and tiredness.
But she. She was different. She walked into his life unannounced. She walked straight into his heart. She did something no one had ever done or attempted, she lit up his heart.
One day closed off, the next set ablaze by her.

He was confident he could make her happy, he was confident that would make him happy too.

She had problems from the others,
ones that she carried on her back every single day.
Loneliness, anxiety, and distrust were only a few animals that she carried each day.
He wanted to help her, he wanted to keep her happy.
He slowly took on a little of each, to help her carry that heavy load.
Soon he took those problems as his own, she unwilling, and unknowingly was destroying him.
He needed an out, he couldn't stay. He decided to leave and breathe for himself.

He lied to himself constantly looking in the mirror and seeing his fake reflection.
The reflection was perfectly fine, so he was too.
But in truth he was hurt, tired, and lonely.
New problems that arose for him were solitude, lonesome, and silence.

He realized he needed her back.
He loses his freedom when he returns to her, he can no longer fly.
But instead he gains a grasp over his problems, and knowledge of his time apart.
But did the girl who burnt his heart and set it ablaze, make him happy or content?

Did she really heal him?
