Right after her birth, Jeong-Yeon was abandoned in a trash can. She grew up with criminals in a hideout. There she learnt how to ‘steal’, she would steal whatever she needs to survive. That’s how she became a thief through her life. No sense of moral ever interrupted her act of stealing. Moreover, she never even thought of stealing as bad. Just like animals hunting to survive there’s no morality involved, Jeong-Yeon was stealing for her own survival. Survival was controlling her morality since it was her only reason to exist.
But one day she met Suhan and Seungha, those who were abandoned from their family just like herself. She took them to her place, like she was destined to do so.
