Moon Song-Jin was born in Seoul, Korea to Lee and Ji Woo Song-Jin. Lee was a from a long line of Hwarangs which was an elite warrior group in Silla that ended in the 10th century. While the Hwarangs were no longer a group, the philosophical traditions and practices were passed down through the family making them a respected family by how they behaved. As Lee came of age he took to Law School and became a lawyer and international business man. Ji Woo was known as the Crimson Flower in Korea, due to family name being Jinhong and her beauty being known far and wide. She was also a renown dancer and practitioner. A few years after the two were married they had their first child, Moon Song-Jin. Named after his mother's favourite song. From birth it was clear, Song-Jin Moon was a cheerful boy who loved to laugh and bring joy to the world. He also was very daring, getting into places a baby wouldn't normally be able to and appearing on top of things that seemed impossible for a young boy. It should also be mentioned, both Lee and Ji Woo were non magical people. They had no knowledge of magic, but would later learn Lee's cousin was a witch, but had hid it from the family and even her husband successfully all their lives. When Moon, mostly known as Song-Jin, was 2 his little sister Seo Yeon was born. Moon was very protective of his sister, but also growing up she was the center of many of his jokes or pranks. While she was the more serious of the two, she also inherited their mother's more gentle and caring side and so the two rarely argued with one another. One day, when Moon was 8 and his sister was 6, they were in a fight about who was could climb a tree faster, Song-Jin lost to his sister and in anger turned her hair pink. Seo Yeon was both scared and angry and she made her brother's hair completely fall out. While weird things seemed to happen around the kids, this was both in a public park and blatantly a show of magic infront of none magic folk. Korea's Ministry of Magic was quick to respond and wipe the memories of the people in the area and get the kids and parents to a more private area. They explained to Lee and Ji Woo that their children were born with magic and Lee's cousin was called in to explain to them in a way they'd understand and help reassure them their children were normal and even special. After a few months of work and educating, their parents came to terms with it and accepted their children. Moon was presented from his father's cousin her wand. She was from China and remarkably exceptional with magic and was awarded a Cherry wand with Dragon Heartstring which was both rare and hard to use, but since she had turned from magic for love, she no longer needed it. Once the wand was in Moon's hand, it began to put out a light hum and with a swish, blue and silver streams began to swirl around him, but the wand was put away for his protection and until school began. Korea was not a welcoming place to the magical community and were heavy on a witch hunt. To protect his family, Lee accepted a job in London as a name partner for a law firm. In London, both Moon and Seo Yeon  received a tutor to learn English, for Moon this went well, but he still had a heavy accent making him stand out more. While the family was rather wealthy, their Korean linage led to racism from their fellow muggles. This led to both children learning martial arts at a young age. Moon took quickly to Kashima Shinden Jikishinkage-ryū especially the Kendo side of it. Seo Yeon found her stride in Tai Chi and even learned to use it in self defense with borrowed moves from other martial arts. Before Hogwarts, he attended grade school in Korea and then continued it in London. His first week in school in Lodndon earned him the attention of the local bully, but even for a 9 year he was able to knock out the bully in a few moves without hurting him. This stopped the bullying and Moon's natural desire to joke around and pull pranks got him a lot of friends to laugh at his jokes. Their grandmother would visit from time to time to make sure they were doing ok and handling their magic prior to Hogwarts. At age 11 he received his from Hogwarts, with his grandmother and sister he went shopping with his grandmother and sister a month before school began. Saying goodbye to his parents and sister at the train station he left for Hogwarts to be away from his family for the first time for a whole year.
