Levi went through hell at such a young age. His mother, considered as his only family died when he was was around 8 years old. He was brought back from the edge of death by this Kenny the Reaper guy, who was almost like a father to him, considering his lack of parental figures. Once he was even beaten up badly by merchants when he tried to take back his mother's tea set, almost been sold off. So all in all, he had it hard. Though it wasn't all negative.
Soon after Kenny, you also came into his life, trying your best to make it a bit better for him.
At the moment, you were in the crowd, watching the little guy beating up a big man on the streets of the Underground City, with a few bruises on his face along with dirt. As the man hits the ground he stopped but not because of the man he was hitting. Looking up you saw that his eyes were glued at the man who raised him adjusting his hat and slowly walking away.
You knew Levi for years, it was known he had nobody except Kenny, and yet again, the 13 years old Levi was left behind, all alone. He looked lost and heartbroken as he watched the man walking out of his life. But he didn't do anything, couldn't do anything just watching.
As the large group of people splits, it was only you, him, the guy on the ground and the few merchants who had their stuffs nearby. He slowly turned towards you with a pained expression.
