I Was Moved After Dressing up as the Heroine of a Sadistic Novel

After staying up late to read the sadistic novel "Love and Hate Burns the Body", I cried all night for the ending of the male protagonist Xiao Heng. When I opened my eyes again, I became the heroine in the book who poisoned him with her own hands - Su Jinyuan, the subjugated princess of Dasheng. The system made a cold announcement: Regent Xiao Heng must be poisoned according to the original plot in order to return to the original world. If the mission fails, I will be wiped out; if he does not die, the world of this novel that should have been completed will completely collapse. In order to survive, I sneaked into the palace under the pseudonym A Yuan and became his concubine. But the ancestral jade pendant around his waist accidentally activated, allowing me to hear his heartbeat—— I thought he would humiliate me, but what I said in my heart was "Don't be afraid, I won't touch you"; I thought he would be on guard against me, but he personally handed the poison-quenching sleeve arrow into my hand; I thought he didn't know me, but he had been hiding deep love for me for ten years. He had known that I was an assassin who came to kill him, but he was willing to drink the poisonous wine. He smiled and said to me, "Don't cry. After drinking this glass of wine, you will be free." The system urged me to take action, and my mind-reading skills allowed me to see all the truth clearly - he was never the culprit of the country's ruin and family ruin, but my fatuous and unscrupulous father. He blocked arrows for me, resisted decrees for me, fought for me against the world, and would rather become a prisoner from the powerful regent than hand him over to me. It wasn't until the end that I realized that he had been waiting for this poisonous drink. Not to fulfill my mission, but to—— Complete my freedom.
