Jo is a 33 year-old lawyer and formerly called the "Venus" in her hometown. After finishing high school and fulfilling her dream of becoming a lawyer, Jo gains weight and feels she is no longer beautiful. After being dumped by her long term boyfriend on their 15-year anniversary, Jo takes an overseas trip to America for work. On the ride back she faints after too much alcohol, medication and a corset puts her into respiratory distress. Alec saves her and they meet several more times, often with Jo in an embarrassing situation. After finding out the identity of Alec as John Kim, she asks him to help her lose weight in return for not telling anybody about his dual identity. She is a blunt and hard-working person.
