Well, the only story that I can think of with a somewhat similar plot line is The Almighty Daughter Runs the World. But it’s not identical since it’s part of the reincarnation genre aside from the “switched at birth” and “super genius” aspects, and it currently has 87 chapters on here. So it’s definitely not shorter than this story, haha.
Hmm... These 3 have a female lead that's also so very versatile

I've read an incredibly similar story. It isnt as long as this though. Any ideas?
