An AU proposed by GalaxyGay developed more in depth by me. By the age of 18 everyone is given the name of their soulmate, the Soulserver marks the name on their wrists forever. The machine was designed to reduce abandoned children and poverty. When Craig turns 18 he's excited to receive his soul mate but he's not ready to get Tweek, the twitchy blond nuisance in his life.

In a world where your soulmate's handprint will appear over your heart when the youngest is born... A newborn's mark covers up the left side of their body. A twelve year old's mark is a baby's hand. Some people aren't happy and don't approve. Some make cruel remarks.

In a world where the name of your soulmate burns on your skin on the night of your 18th birthday, Minna wanted nothing but to feel the blinding pain everyone around her had described to be nothing short of something continuously stabbing your chest with a hot searing knife. It wasn't like she was craving the pain, no. She's no masochist. What she wanted was to know that somewhere, someone on Earth was destined to be with her. She wanted to look in the mirror and see a name engraved on her chest like it had always meant to be written there for everyone to see. Her 18th birthday came and go, but there wasn't the smallest hint of pain on her chest. No trace of even a single stroke of someone's name on her pale chest. There was nothing.
