She obviously pretends not to care, but why can't her heart stop beating when she sees you again? She obviously promised you not to see each other again, but you risked your life when she was in the most danger. She clearly knows that you love her, but she always doesn't want to respond to you. Because she can't afford to be hurt, she doesn't want to love you until the end, and she doesn't know how long her life will be. She hopes you can forget her forever!
