His Beloved Assassin Maid 01

Dreaming of a return to the Great Chu, Paulina unexpectedly awakens as an assassin suffering from a lethal poison. The sole remedy lies in the hands of her master, who will only provide the antidote if she kills Prince Kellan. In her possession are four transformative pills that, when ingested, can entirely change her looks, body, and even sex. As Paulina starts to grasp the state of affairs in this realm, she is swiftly encircled and detained by the princely mansion's guards.
