Alia is a skilled thief who, in search of a legendary treasure, sneaks into a castle under the cover of night. However, she unexpectedly witnesses the castle’s owner, the handsome and cold-hearted billionaire Marcellus, murder his wife. In the chaos of her escape, Alia is discovered and killed by him. But death isn’t the end. Alia wakes up to find herself reborn a year earlier, this time in the body of the wife Marcellus had killed—Livia. Faced with the man who had once killed her, now acting outwardly kind but still harboring deadly intentions, Alia knows she must uncover the truth within a year and avoid the same tragic fate. Her plan? Escape the castle and steal the treasure. During her time in the castle, Alia discovers that Livia’s identity is far from simple, and she soon finds herself tangled in a deeper conspiracy. Marcellus’s younger brother, Elias, has a close, secret relationship with Livia, one that seems to involve hidden feelings. As Alia secretly investigates Marcellus’s true intentions, she is drawn to his conflicting mixture of gentleness and coldness. At the same time, the body of Livia compels her to develop feelings for Elias, whose tender care for her awakens a sense of warmth. Caught in a whirlwind of emotions, Alia realizes that every person’s motives are more complex than they first appear, and she must make difficult choices between truth, revenge, love, and survival. As the one-year deadline approaches, the conspiracy unfolds, and Marcellus’s true intentions toward Livia are exposed. Alia finally finds a chance to escape. But with emotions tangled and fate inextricably linked to the castle, will she choose revenge and freedom, or will she find redemption and true love within the deadly walls of the castle?

Of course, it did not help that an irritating genius artist, Thomas Saint Clair, was always at her tail.

I am a doctor. One day, I come across a weird patient when I am on duty. The first thing she says when she sees me isn't that she feels unwell somewhere. Instead, she says something hair-raising. "Dr. Cantrell, your girlfriend is a murderer." "What nonsense are you spouting?" I shoot back with widened eyes and shoot up from my chair. I feel offended. She calmly says, "She won't be home tonight because she needs to deal with the body. You will know whether what I say is true by tonight."

After I transmigrate into a Gary Stu novel as the evil male supporting lead, a system appears in my mind. It tells me that as long as I can conquer one of the female leads, I will be able to return to my original world with a healthy body. But I've failed in my conquest. There are a few female leads in this novel. There's the fake heiress, Leslie Jackman, who I have grown up with and have viewed as my older sister. The true heiress, Miranda Suller, is a boxer who happens to be seatmates with me during our high school times. My childhood sweetheart, Catherine Langdon, who's also a genius surgeon, happens to be one of the female leads too. Heck, even my own daughter, Natalie Jackman… my own flesh and blood… All of them are quick to fall for Gabriel Linner, the poor yet strong-willed young man who's also known as the Gary Stu of this novel. Because of that, they hate me deeply. The system sighs before telling me that as long as I can die in the hands of any of the female leads, it will let me return to my original world. Later on, I use all of the tricks up my sleeve and succeed in getting killed by the female leads. But why is it that they've lost their minds after I die?
