ah, so we once again have a white lotus B* on our hands. This one seems to like playing cute and pitting siblings against each other and keeping the fish (men) in her pond. Sigh. I had hoped she was as nice as she looked, but guess not.
Villainess stories where it just swaps the villainess role with the original female lead are so tiring. It's harder to enjoy redemption arcs and subversive kindness from supposed antagonists if you're devoting time to also destroying the supposed protagonists' image with subversive evil - the end result is hardly different from swapping the FL and villainess' names and calling it a day.
I understand the urge to make the subversion "more complete", but it ends up turning otherwise compelling stories into structurally identical reflections of the things they're trying to parody.
Maybe one of these days we'll have a story about somebody transmigrating into the original FL of a villainess story and befriending the transmigrated villainess instead of this "but what if i jist shuffled the actual villainess tag onto the original FL, nobody will expect that!" tripe.
