Becoming Princess Knight and Working at Yuri Brothel

Soushi Naruse is a 38-year-old political secretary. One day, he is caught in a car accident, and his vehicle is swept to the bottom of the sea—with himself in it. At the same time, in a completely different world, a princess named Reina is caught after her kingdom is taken over by another country. Her retainer, with no other options left, decides to save her soul by taking it out of her body. Searching for another soul to replace it, she chooses Naruse's. And so Naruse—now in princess Reina's body—is taken prisoner and sold to a lesbian brothel. Taking up the name Lillion, our protagonist decides to embrace being a prostitute and rise through the ranks, to both attain a more comfortable experience as well as figure out the mystery behind Reina's past.
