Su Qingci, who was "abandoned" by Lu Shiyan five years ago, saw him being intimate with a woman named Lin on a rainy night, but was forced to become his subordinate due to livelihood constraints. The two faced off and protected each other many times during project cooperation, their father's serious illness, and conspiracy pursuits. The truth was revealed layer by layer: the breakup was a misunderstanding, the Su family's bankruptcy was a frame-up, and the culprit behind the scenes was an old grudge intertwined by multiple forces. From confrontation in the workplace to life and death rescue, from suspicion and alienation to rebirth of trust, Su Qingci and Lu Shiyan went through kidnappings, explosions, secret rooms, and family secrets, and finally worked together to destroy the "ghost" organization. However, when ring engravings, mysterious women, and late-night secret meetings emerge one after another, new doubts are shrouded again... Love and conspiracy are intertwined, and the truth is far more shocking than imagined.
