Secret Lady

A child who has the ability to see ghosts, Yoon Seol-woo. Has reincarnated into Rosantine, a princess who could see ghosts. I have managed to fake not being able to see ghosts somehow but... "Leave my sibling body this instant!" I cried out to the spirit who possessed my one and only little (brother/sister). However, only the death penalty awaited for me if my ability were to be found out. Then, there only one way. "You are planning to kill Prince Chartus, right?" I will save the Empire second prince, Prince Chartus with this ability! "I will bet my life on Your Highness."
