Honestly, you don't think I'd have to put up a disclaimer every time I write a story...But I might as well.
I don't own Fullmetal Alchemist; just merchandise.
Lights will guide you home.
For the two infamous brothers, that statement does not apply.
They have no home to return to.
They had lost everything in their claim: the care of a parent, their sense of touch, and the warmth of a house they can call their own.
Unknown to their knowledge, there was the house of the waiting family.
There was a girl who flicked the lights once in a while. She was always on the second floor balcony, yearning for someone to come back. In a sense, she had wished to resemble the actions of their late mother. Her wish came true.

Long, but not so long, ago, there was a family.
In fear of endangering the lives of the ones he loved, the man left his home.
The woman named Trisha had prayed for the safety and return of her beloved husband. Whenever her sons stayed out too late, she turned the lights on and off by the second story window to guide not only her sons home, but her lover as well.

As much as the automail mechanic desired for the protection of the Fullmetal Alchemist and his brother, they always bear an injury or more. They would return to their hometown, to the house of the waiting family, either for maintenance, food or shelter.
Though, the importance is that her lover and his younger brother always returned.
For after all; they have a home to return to.
