Vivian Walker decides to change her future by rejecting her lifelong plan to attend Quinby University like Isaac, the man she once loved but who ignored her. She chooses to enroll in National Defense University instead, determined to live independently and contribute to her country rather than chase a romance that caused her past misery. Despite her resolve, Isaac confronts her coldly after she sends love letters, telling her their relationship was never meant to be and demanding she suppress her feelings. Vivian accepts this hard truth but vows to live for herself, leaving their complicated connection unresolved.
