Out of recognition for my achievements in the medical field, I've been made a member of the prestigious International Medical Institute. I return to the country after that. Yet, on my very first day at work, my niece, Angie Judd, ends up dying tragically in my ward. When she's found, the lower half of her body is covered in a sticky substance, and part of her uterus has dropped down. Her mother, Melanie Larson, has an emotional breakdown and jumps to her death. Her father, my adopted younger brother, Cody Judd, furiously stabs me in the abdomen. My wife, Serena Thompson, calls me a monster and immediately files for divorce. She ends up marrying Cody the moment the divorce is finalized. To make it up to Cody, my father, the police commissioner, uses his connections to forgo a proper investigation and have me imprisoned for sexual assault. My mother, the CEO of a company, takes it upon herself to transfer all of my assets to Cody. She also helps him become a renowned billionaire philanthropist in Crestbay. With no way of defending myself, I end up spending eight years in prison. The day I finally get released from prison, the entire family shows up at the prison entrance to wait for me. Serena, who's now my ex-wife, approaches with reddened eyes to hug me, but the look of concern on her face seems so fake to me. "All that matters is you've come back to us now, Hector. From now on, I'll always be by your side." The moment she finishes speaking, the nearby civilians swarm all around me. "Hector Judd! You got lucky with just an eight-year sentence! You should've been castrated and shot to death!" "That's right! To think you even hurt your own niece! You're a monster!" The endless torture and abuse I'd suffered in prison have left me feeling rather dazed. Eventually, a man who had once received financial aid from Cody rushes up and throws a bucket of sewage water at my face. "You monster! Mr. Judd even had to cancel his celebration party today just to welcome you home after your release from prison! You killed his wife and daughter, ruining his family, and now, you're even stealing the rest of the only family he still has? Go to hell!" Inhaling the putrid stench, I let out a sneer. They were the ones who falsified the evidence to throw me in prison back then. They broke my legs and injected me with a neurotoxic drug that addled my brain, making it impossible for me to protest. They did all of those things just to cover up the fact that Cody is the real murderer!

When I died with a smile on my face, right before my brother's eyes, he looked as if the anguish might tear him apart. Yet, for twenty-one years, he hadn't stopped wishing I would meet this exact end. It all traced back to my fifth birthday—the day I had innocently hoped our parents would come home from their business trip to celebrate with me. They rushed back that night but never made it. A car accident took both their lives. From that moment on, my brother resented me, despised me. He didn't just stand idly by as our cousin snatched up my work as her own; he encouraged it. And when my landlord threw me out, it wasn't a random cruelty—it was my brother pulling the strings. All he had ever wanted, from the very beginning, was to see me die a miserable death. But when he finally got his wish… why did he cry, pleading for me to come back, begging me to call him 'brother' one last time?

I vividly remember sometimes, remember that I run from someone " I did that in order to survive, They always treated me like a monster" I remember his words that he shouted clearly in my mind, but who said that ? And why? Why he was running after me?
