Crossing the Line of Love

Pei Duan Yan secured the position of president of her family business with a marriage contract, her motto being "calm and restrained." Her biggest trouble was her fiancé's mistress, Yu Songzi—a captivating and troublesome woman who, under the guise of a "stepsister," had infiltrated her household as her subordinate. Pei Duan Yan firmly believed that Yu Songzi was there to destroy everything she had. Therefore, she coldly warned, "Please call me President Pei." But when Yu Songzi's fingertips brushed against her collar, she froze, unable to push her away. This was an extreme game of "the body always speaks louder than the mouth," until they could no longer distinguish whether those entangled days and nights were a surrender or a victory.
