Having her second son born into the slums of Paris wasn't what Maeng Hae-Young had wanted, but that's what destiny had planned for Charles Kang. Whilst his mother and brother knew a life of luxury beforehand, Charlie only knew of the one bedroom studio apartment that they all attempted to cramp into and thus never complained, especially when paired with a doting older brother, Charlie saw no faults in life.
Unlike his older brother, Charlie was home-schooled and was fiercely protected by his mother. She brought him to do everything with her, rarely trusting anyone with him. It all seemed to be going well until there was a dip in the family's finances and Hae-Young was forced to choose between the two of her sons and which to give to her mother to look after. Fearing negative experiences with Laurent, she gave Charlie to her mother to look after in hopes that his well-being would be protected.
Charlie continued to have a good life in the care of his grandmother; having been four at the time he wasn't fully aware of the situation and only really knew that he had to stay with his grandmother for a while until his mother could house him once more. I guess the saddest part was that he never returned to his mother and didn't do so until after he started Hogwarts. Regardless, his grandmother experienced his first magical experience with him when he was eight. It wasn't massive; just making the fruit bowl explode, but it was enough to ensure that he'd follow the magical lineage. Unlike Sammy, Charlie didn't inherit his father's metamorphagus gene and, like his mother, was only a wizard.
When he was 11, Charlie received a letter of acceptance from Hogwarts and chose it over Beauxbatons, being sorted into _____ house where he's been and flourished (in everything but height) ever since.
