Choi Jin-sil
Maeng Soon-yi (Choi Jin-sil) has sacrificed everything in her life for the sake of others. She missed out on her youth because she was too busy taking care of her father (Jang Yong), who started drinking heavily after her mother abandoned them when Soon-yi was 10 years old. Soon-yi gave up on her own education so that she could earn the money to pay for her younger siblings' tuition.
