I Go Wild in a Mary Sue Novel

[Transmigrate into a book + both are virgins + hilarious jokes + satisfying revenge]

Blurb One:

Lin Shan, whose life had never gone her way, transmigrates into the real heiress who was switched at birth by a crooked nanny. Returning to a wealthy family, she thinks she’ll live a life of luxury, only to find herself plunged into utter madness: a brainless father, a biased mother, a scheming fake heiress, and a spoiled younger brother. Fine, fine, you really want to play it this way?

On the very first day after reclaiming her identity, Lin Shan drops all pretenses and starts going off the rails. If not now, when?

Blurb Two:

After transmigrating into a fake-strong-female-lead, real-Mary-Sue novel, Lin Shan doesn’t expect to meet a single normal person. Sure enough, the heroine acts like a supreme commander, with every supporting character jumping wherever she points. The male lead is rich, dumb, and convinced that his domineering love is irresistible. And the second male lead isn’t any better... Wait, the second male lead actually seems normal.
