After the Eldest Princess Exchanged Souls with the Border Girl, She Went Crazy!

[Misplaced Identity] + [Strike] + [Strong Woman] + [Fate] + [Mutual Trap] + [Soul Exchange] I once thought that the deep palace was my prison and conspiracy was my destiny. Until that day, I became her A "princess" who is unfamiliar with holding a knife in the wind and sand at the border. But she, the soul that truly belongs to Border Gate, is trapped in my golden prison. Using her set of rules of "either you die or I die", she clumsily dealt with the smiles in the court. Our souls are exchanged randomly and without reason, as if God has played a bad joke. Yesterday she drew a knife and stabbed someone at the banquet, and today I had to hide in the rain of arrows with her weather-beaten face. We dislike each other and leave each other a mess, but we have to grit our teeth and survive for each other until the next time we "come back." Because we know better than anyone else that this body is our common and only way to survive. This misplaced struggle, this absurd fate... Can we really find ourselves again? This book is also called "About the incident where I exchanged souls with a tough girl from the border and went crazy in the palace," and "My brother is always afraid that I won't be able to use my knife when killing people." High-energy reversal, extremely cool, the power-scheming palace fight cannot stop!
