Fate Stolen. I Rose As the Beast World's One True Queen

I was diagnosed with Wolf-Soul Decay Syndrome on my birthday, which meant I was on the verge of death. But my older brother, Alaric Sinclair, bought the only tube of Moonviolet serum—a serum capable of saving my life—just so he could give it to my younger adopted sister, Megan Sinclair. He thought I faked my illness in order to attract everyone's attention. Because of that, I stole the serum when no one was looking and took it. That night, Megan drove away from home in tears, only to be met with a fatal car accident that took her life. I was cast out of my childhood home by my parents. Even my fiance, Kenneth Ravenscroft, who once vowed to protect me, hated my guts. Upon returning to my own home, I ended up dying in a fire that broke out. But what I don't expect is that I've traveled back in time to the third day before my demise. During those three days, I've given up on everything. When I mention that I can give away my spot at the marking ceremony, Kenneth praises me for being an understanding fiancee. When I hand over my design company, which is in the top 500 rank, to Megan, my parents are satisfied with me. "You've finally learned how to be selfless, Evie," they say. But Alaric grabs my hand and roars, "Didn't you claim that you'd never give those things away unless you die? Why are you giving them away now?" That's because I'm about to die, dear brother.
