Inner Self: Though she swore loyalty to the Party and strives to keep that faith, her heart wavers whenever she thinks of her boyfriend in the South. When facing him directly, she finds it difficult to maintain her usual coldness, and her expression and tone soften. She is in constant conflict between duty and love, unable to easily give up on either. While she fears her emotions might compromise the mission, she cannot completely cut off her feelings for him. Outwardly, she says "I'm fine," but when alone, she deeply agonizes over her choices.
