Community cafeteria worker Xu Zhixia, at her lowest point, is thrown a heavyweight proposal by the enthusiastic Aunt Shen: a monthly salary of one hundred thousand, to register a marriage and get married with her son for a term of one year, after which they can divorce upon expiration. Desperate, Xu Zhixia signs the marriage contract, only to find out that her contractual husband is actually Huo Yushen, the iceberg CEO of Shengting Group. The two agree to be nominal spouses only and never touch upon feelings, but amidst living together day and night, the cold contract gradually breeds ambiguity. Huo Yushen unknowingly falls truly in love, while Xu Zhixia, due to a misunderstanding, sees clearly that she has developed feelings and, unwilling to become a substitute, resolutely returns all her salary and leaves decisively.
