I agree with your review.
In the movie~{#,~}she lost her virginity for the mission to serve her country. In Chinese culture that's a big sacrifice for a virgin considering virginity is still valued a lot today in China and probably it was more back then. She obviously chose her mission for her country over her own personal loss. However~{#,~}in the end she had to choose between either her life or his life~{#,~}between either fail the mission she it supposed to accomplish or let him go~{#,~}she chose to let him go only because she thought he loves her. for him or we can say for his love~{#,~}she chose to lose everything.
I believe the director wanted to show that he has feeling for her. one is she sang for him in the Japanese restaurant~{#,~}he had tears. another may sound materialistic~{#,~}but hey~{#,~}sometimes it doesn~{!/~}t admit it or not that's the way we look at things-- he bought the diamond that he would not buy for his own wife.
I believe she probably didn't plan to fall in love with him. Her task is just to have him killed. but in order to gain his trust~{#,~}she had to play this dangerous game not only with her body but also with her heart~{#,~}she opened her not only her but also her heart to him. she must made herself venerable in order to complete this task~{#,~}but this venerability is fatal to successfully carry out this task when she falls too deeply emotionally~{#,~}so she fell and failed.
The movie also depicts that she lost her mom early and doesn't get much love from her father and family. she was on her own there~{#,~}but the love she received from Mr. Yi is actually something she probably~{#,~}actually every woman or man~{#,~}yearns to have-- to have someone deeply love you~{#,~}value you and care you. for a person like her who doesn't get so much love from any place else~{#,~}the lack of emotional care makes her more venerable to sacrifice for love or heartfelt emotions she receives.
In zhang ai lin's novel~{#,~}it says it's hard to love for a girl like her because she is strongly immune to be moved by love. I agree~{#,~}good-looking girls normally are difficult to fall in love and trust men.
so for her~{#,~}on one hand she longs for love and care because it~{!/~}s lack in her life~{#,~}but on the other hand she cautions against men~{#,~}however~{#,~}even the most strong-minded girl/woman~{#,~}she will give in to someone if the right person moves her and opens her heart. once she does~{#,~}she gives all she has. so when choose between her life or his life~{#,~}she chose to die for him.
This is a woman~{!/~}s tragic love story.
