偽令嬢の訳ありオークションカタログ エメラルドは出会いを導く

Aire, a girl with a special sense of beauty, discovers that a forgery is mixed in with the merchandise at one of the auctions. This leads her to help Bartoluto, the head of the young marquis family that runs the auction! In an unfamiliar world, Aire is at first unable to rely on others properly, but he eventually opens his heart to Bartoluto, who offers his help even though he is clumsy. At the same time, he feels uncomfortable with Bartoluto's unusual fixation on the authenticity of things. The reason for this seems to be deeply related to the reason why he organizes auctions...?
