It was only on the verge of death that I realized I had been deceived by my perfect twin sister my entire life. In the shock of betrayal, I wished to simply let death take me... but when I opened my eyes, I had returned to my childhood!? I have to act as a single princess alongside my sister, without anyone finding out we're twins! Now that I’m back, I refuse to live my life being manipulated by her like I was in my past life. The relationship with my family that I yearned for, and the friendships with my friends. Even the healing power I never knew I possessed in my past life. I will make them all mine! In the midst of it all, I happened to meet a talking bird named 'Yan'. It says that if I don't protect it, the kingdom will fall to ruin. What is that supposed to mean? Will I be able to survive this time around?
