Trust me on this. Female leads are both entrepreneurs who hate being walked all over... Both MLs fall first and fall hard! They both struggle with class differences too, just trust me and watch.

Smart and business-savvy female lead. Both FL's have calm temperament and approach their problem and family matters/concerns with a composed attitude. Both are also have good relationship with their grandfather's. The male leads are both dependable men and apparently common with the double identity trope. The ML's hold high positions in society but have a complicated distant connection to the palace/imperial family. In short, both dramas are about, double identities (male lead) and business/merchants (female lead).
