I Really Never Meant to Become the Blood Spirit Princess

[Transmigration + gender transformation + unconventional Western fantasy + white-haired heroine + Blood Princess] Other people transmigrate and become heroes. Lu Chen transmigrates and becomes a princess. Lu Chen had thought he would become a hero, marry a princess, build a harem, defeat the Demon King, and reach the pinnacle of life. But not long after he arrived, he was turned into a little Bloodkin princess by her progenitor. And just like that, he got himself a bargain mom. He hadn't even married a princess, and now he'd become one himself. Still, it wasn't all bad. Maybe he could live a carefree life where meals were brought right to him... That is, until she realized there seemed to be something else living inside her mind. Three people who had no business appearing in a Western fantasy world, three figures practically ancient enough to be her ancestors.
