Born into a low income family, Byeol was supposed to be the star child who got them out. Her family's dreams came to a startling halt when Byeol was three. Her tantrums were so much more than a simple tantrum. There was no stopping them. Most children stopped when they got what they wanted, not Byeol. The older she got, the less she acted out. Her parents thought that maybe there was still a chance, but they didn't see what she did. They didn't feel the things she did. Byeol was her parents biggest regret. Once she turned eighteen, she up and vanished. She couldn't stand bringing pain and suffering to her family. That's all she's ever known, and the last thing she wanted was for them to feel how she did all these years.
