Aurora was born in a cold winter morning at San Francisco to a couple of half-blood, second generation Korean wizards in America. The couple already had a five year-old daughter named Jasmine at that time and the baby was named Aurora by the big sister because she loved Disney Princess.

Being a second-gen Korean makes Aurora and Jasmine grew up in both Korean and American cultures, that includes the language they're speaking. Little Aurora was more fluent in Korean than English, until at the age of four when she joined a daycare. She grew up as a happy go-lucky little kiddo and didn't feel inferior despite of her being an Asian in the middle of her circle of friends. Besides from daycare, little Aurora and Jasmine were also being tutored about wizarding world by both of her parents who both were professors of Education department in Wizarding University. At the age of six years old, the Chae family moved to Boston since the wizardry community there is way bigger than in SF. Aurora went to wizarding primary school while her sister went to Ilvermorny.

She got her acceptance letter from Ilvermorny at her 11th birthday and hoping she could be in Horned Serpent, just like Jasmine. But the Gordian Knot decided to put her in Wampus and she was not really happy with that. Slowly, the traits of Wampus grown on her. Her years at Ilvermorny was nice, she made many friends and were quite known by some of Wampus students. At her third year, she got her first kiss from Miguel Martin, a horned serpent guy who was a year older than her. Eventually they started dating for a few months, until Aurora realized that she might be attracted by both guys and girls. Later on Miguel broke up with her and she told Jasmine about her sexual confusion. On her fourth year then Aurora came out to her family as a bisexual and thankfully they're very supportive about this.

On summer 2097, Reginald found out he's being offered a position as a vice dean at WU London and was torn either to accept it or not since the Chae family had been settled in Boston for a good nine years, but Jasmine (who had moved to Great Britain since she's going to Edinburgh WU) convinced him to take the position. So their family moved to London except Aurora decided to settle in Ilvermorny due to the difference system of school between Hogwarts and Ilvermorny. Eventually on Christmas she decided to not go back there and wanted to be with her family in London. Since fifth year in Hogwarts is OWL year, Aurora was homeschooled to get an intensive tutor for her exam preparation. She earned eight OWLS with satisfying result and now ready to go to Hogwarts.
