Arthur lived a traumatic life since childhood. Being bullied, and detested for his innate talent. He was a good kid with talent in the most, the three things one would commend him for, not to forget target and bully him for would have been his talent for reading, remembering, and judgementalism. Not to leave aside his amazing adaptability in sports and physical activity.
He was quite an antisocial person despite his talents, the only friends he had were his siblings Elric and Sophia.
Elric was the oldest and Sophia was the youngest sibling. They were a team..they supported each other.
Arthur's father had worked in the military and had died in a mercenary mission after he had died their mother couldn't work enough to pay their bills and loans, this forced them to move into their uncle's house.
His uncle was a bipolar abusive man, capable of disappearing in his bedroom for days during the depressive phase, it made Arthur understand while his uncle at the phase when his life was good never was around in any family gatherings and parties.
His uncle would only wake up only to eat, use the bathroom. During his euphoric phase, he would work like a madman, but not having any talent either as a businessman or as a social climber, he was unable to both be successful and establish the right connections.
In his natural state, whenever he decided to actually take his medications, he was just a couch potato that would stand up and go to work just to avoid the blame and spite from neighbors and peers. Whatever was his mental condition, he always was a perfect example of an abusive father.
The Hendrikson siblings hated their uncle, he would yell at their mother for the slightest mistake, constantly reminding her that she was just a parasite that leeched off his hard work, despite the work she did in the house.
She was the woman who cleaned the house morning-to-night, made his food, and made his stay inside the house enjoyable, despite his bipolar complex. He was abusive, he would wake them up in the night with his screaming, ordering Arthurs mother around.
He'd throw away abusive words at her, even sometimes threatening to hit her..his own sister?
The thought of being related to him was sickening:
"You never studied hard enough, you lived off your husband's back. After he died you, worthless woman, can't even get a job...Your just those average sugar daddy chasers!"
"Woman, where you never were disciplined enough, I let you live here and here you are complaining...better get your ass functionin' or you can get packing!"
"You never show enough respect, ill slap that face of yours! Honestly your a disgrace to be a sister of!"
Who was he..?
The uncle didn't show mercy to the kids, he would yell at them for the slightest mistake, constantly reminding them that they were just parasites that leeched off his hard work.
And when words weren't enough or when they did fail to meet his expectation with school grades or chores, there was no teacher like his leather belt.
Hence, Arthur, Elric, and Sophia had to quickly learn how to fend off for themselves, since their absent-minded mother practically forgot about them for most of the time right after moving into the house, dedicating her life to pursue making her brother (their uncle) happy, so they could stay.
Elric was three years older than Arthur, and Sophia desperately tried to take care of his little siblings, but to no avail. He would be outside for a long coming home at late night.
By accident..of course, Arthur had caught his elder brother sneaking inside his mother's room, and smuggling big bunks of what look like cash inside her cupboard.
