He Chu Feng and Luo Bin are two of the most eccentric antique store operators in the business. They live together in the same house with only a large cat for company and have become quite accustomed to each other’s bizarre quirks. Neither of them has had much success in their love lives, but that doesn’t bother them too much. He Chu Feng is a man of mystery and is the store’s locksmith extraordinaire – able to open any lock imaginable on a range of antique pieces. Luo Bin is the master appraiser of the duo – a man capable of assessing an antique’s worth in mere seconds.
But things are about to change for them when two women come into their lives. The first is a trainee lawyer named Sui Yi. The duo agrees to let her live with them, which forces them into an unfamiliar routine of housework. This also sparks a somewhat unconventional fledgling romance between the positive and personable Sui Yi and the ever-enigmatic He Chu Feng. Then, an ace auctioneer named Fang Qi comes to seek help from the housemates.
Luo Bin falls in love with her at first sight when he sees her suffering from an injury and in need of assistance. Is it possible for romance to change the atmosphere of this antique store?
