He ChuFeng and LuoBin are the two oddball operators of Monster Vintage, a notable antique store. They live in the same house together, with only a large cat for company, and have become accustomed to each other's bizarre quirks, although their respective love lives are nothing to write home about. 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. And Luo Bin is the master appraiser of the duo - a man capable of assessing an antique's worth in mere seconds.
