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’ve managed to fake not being able to see ghosts somehow but…“Leave my sibling’s body this instant!”I cried out to the spirit who’s possessed my one and only little sister.However, only the death penalty awaited for me if my ability were to be found out.Then, there’s only one way.“You’re planning to kill Prince Chartus, right?”I will save the Empire’s second prince, Prince Chartus with this ability!“I’ll bet my life on Your Highness.”Credit for the summery : Rin.rinaaa
