To take back the company that belongs to her, Shen Qingci resolutely enters a flash marriage with Xi Xingye, the rumored eccentric young master of the Xi family. The two set down eight rules for the pact, agreeing to mind their own duties after marriage and not interfere in each other's private lives, intending to get what they each need through a contract marriage. Unexpectedly, on the very first day of the new marriage, Xi Xingye breaks the agreement. Through living together day and night, the two go from probing each other to supporting one another. Xi Xingye silently guards her, while Shen Qingci reclaims her business territory with her strength. This relationship that began with a contract gradually breeds the warmth and growth of moving toward each other from both ends.
