Facing her snobbish parents and hostile adopted sister, she gradually conquered her eccentric family members with her hacking talent, extraordinary courage and kind nature. She exposed conspiracies, punished evildoers, and repeatedly achieved miracles on campus and in shopping malls. Not only did she gain the sincere love of Mr. An and her brother, she also found her biological parents. This journey full of growth and warmth witnessed how a border girl became a treasure protected by everyone.
