True heiress and fake heiress, sweet and sassy, scheming and vengeful, secret-identity wish fulfillment, strong female and male leads, cherished by everyone, deep sisterly affection, no evil female rival.
The true heiress looks like a pure, well-behaved girl and can be sweet or sassy, but beneath the surface she’s calculating and never lets an offense go unpunished. The fake heiress is gentle, kind, and genuine, and the sisters get along harmoniously. The whole family dotes on everyone equally, with no favoritism. The male and female leads are evenly matched and choose each other wholeheartedly.
