One day, I get lost in the forest. Frozen out of my wits, I accidentally barge into the Bloodmoon pack.

From that day onward, Raul gives me everything he has. He gives me the spot next to him as well as the pride and glory of being the she-wolf who has power over the other wolves in the pack. Every look Raul gives me is filled with hot, passionate love. Every touch proclaims his possessiveness toward me. I used to think that I've finally found my actual home.

But five years later, Raul brings back another she-wolf named Eva Grayback after surviving a battle at the border. As he stands before the pack with his hand intertwined with Eva's, he declares solemnly, "Eva is my actual fated mate." As for me? I'm nothing but a liar.

That's why he must rectify this mistake. On the day before Raul and Eva hold their bonding ceremony, I'm tossed back into the forest. The beasts' fangs tear through my flesh, while wolfsbane burns in my blood like fire. When Raul finally dispatches a squad to look for me in the forest, everything is far too late. I've already remembered who I am and have awakened my hidden potential. That's when I decide to leave him with the unborn pup in my belly.

The first thing I did after being reborn was add penicillin, a drug the patient was severely allergic to, into his pre-surgery medication administration record. The hospital leadership exploded. “Have you lost your mind?” “Are you trying to kill the patient?” I smiled as I accepted the suspension notice they handed me. In my previous life, I had been the lead cardiac surgeon for this operation. Back then, I refused a request from my wife, Shannon Wright, whose childhood friend, Jonah Hill, wanted to use my patient as ‘practice’ during the surgery. Right there in, Shannon threw a tantrum and demanded a divorce. In the chaos, she ripped out the patient’s blood transfusion line and even knocked over the blood bags, causing the wealthy patient to die on the table. However, they pinned the entire medical malpractice scandal on me. With the security footage wiped clean, I was sentenced to death in the end. My parents sold everything they owned and gathered eight million dollars. They gave the money to Shannon, begging her to hire a lawyer and help overturn my case. Instead, she told them that she and Jonah had been having an affair. From the very beginning, I had only been their scapegoat. The shock shattered my parents. While driving home in a daze, they lost control of the car and plunged off an overpass bridge. Both of them died on the spot. Now, when I opened my eyes again, I had returned to the very day of that wealthy patient’s surgery.
