Quick Wear, the Villain King's Pet in the Palm of His Hand

I am a raider who travels through countless dungeons. My mission is to make the villain king who has just ascended the throne fall in love with me, and then kill him with my own hands when he trusts me the most. I thought it was an easy task, but when he slaughtered all the people in the palace for me and responded sincerely, my heart was moved. I accompanied him from the bloody road to the prosperous age, and became pregnant with his child, thinking that I could stay by his side. But at the end of the rebellion in the court and the sharp knife piercing my heart, he hugged me and said with his last breath: "This time, I will send you back in person." The moment the system prompted that the task was completed, I realized that from beginning to end in this strategy in the name of love, he had never been the loser.
