 She then played the titular character in "My Daughter Seo-young", a career woman who is angry at her father (Chun Ho-jin), whose gambling addiction led to her mother's death, yet she struggles to keep the family together and make ends meet.Lee said playing Seo-young required a greater depth of emotion than any of her previous roles, which left her drained but also feeling a greater sense of achievement.The family drama was the biggest hit yet of Lee's career; it dominated the weekly ratings chart for 22 straight weeks, and recorded a series high of 47.6% on its last episode, the highest Korean drama rating in 2013.
