Su Wan was forced to marry into the Gu family and became Gu Yanchen's nominal sister-in-law. She also accidentally joined his department and became a subordinate. Living under the same roof, in the same workplace, and the taboo identity of uncle and sister-in-law + superior-subordinate relationship made Gu Yanchen restrained and out of control. While he was protecting her as his "brother-in-law", he was favoring her as his immediate boss and getting closer step by step. After Brother Zha committed suicide and got divorced, he completely tore off the label of "brother-in-law" and pampered his sister-in-law into his exclusive wife. Su Wan also made a counterattack from a novice in the workplace to a gold medal designer.
