Not only does he rescue her, but in gratitude for her saving his sister, he personally takes care of her amidst his busy CEO life. As their relationship deepens, she finds herself in a dilemma: he wishes to treat her as a "sister," and even his parents have taken her in as such. Troubled by this, she insists she doesn’t want to be his “sister”; she longs to be his “wife.” This mismatch of love and identity sets her on a journey filled with sweetness and complexity. Will she be able to break free from the "sister" label and win the heart of her prince charming, stepping into their destined happiness together?
