I'm looking for a novel where the mc transmigrated as the hidden boss. I don't care whether they're a male or female mc, nor do I care if it's a straight romantic story or an LGBTQ one. The only thing I care about is that the MC transmigrates as a hidden boss, and DOESN'T make themself one like To Be a Power in the Shadows and There Was No Secret Organization to Fight With, etc.
The Other Side of the Last Boss Level 99 Villainous Daughter These are the only two I know that fit what your asking for.
