Backstory: Mellow Marta (actual name- Dolly Gemma Marta) was born in a  middle class neighbourhood. Her mother left her at a very young age and left her with an angry drunk of a father. She eventually became addicted to drugs and alcohol similar to her father, and barely got by day to day, rotting in her own body. One of her only escapes from this life was her interest in art. She died of pneumonia at a fairly young age and woke up in hell.
