In her previous life, she trusted the wrong people and tormented the man who loved her most.
She gave up studying the medicine she loved for a worthless man, then married into an enemy kingdom and spent six years undercover to help him. She fought on the front lines, killed the enemy, secured the border, and captured cities. Yet in the end, her entire family was executed, and her home was destroyed. As she lay dying, the man she had tormented until he was covered in wounds came alone, willing to die alongside her.
Reborn into a new life, she will master both medicine and poison, and swears to kill her enemies with her own hands and make every scoundrel pay.
This time, she will no longer live for her country and its people. She only wants to protect her family and the one she loves, and will never repeat the mistakes of her past.
