Who Is The Main Character In Building A Second Brain?

“Who am I supposed to be this time… the boy they love, or the man they lost?” Eli, a 25-year-old orphan, finally lands his dream job, only to lose his life in a sudden accident. He wakes up in the body of a 19-year-old heir who shares his name, a powerful family, and a life that is far from perfect. Soon, memories begin to surface. Not only his own, but those of a young CEO who was betrayed and murdered by the people closest to him. Caught between lives that do not fully belong to him, Eli must navigate a world of wealth, secrets, and revenge while facing people who love him for different reasons. As the truth unfolds, he is forced to question who he really is and whether this second life is a chance to start again or a trap he may never escape.

The day my rich parents come to claim me, all eight of my godfathers weep while sending me off. But just two days later, because I score a whole hundred points higher than the fake heiress, Sharon Staton, on a mock exam, my parents drag me to some black-market underground hospital. They want to dig out my brain and transplant it into Sharon. "With your return, Sharon is no longer the only princess in our family. Giving her your smart brain is the least you can do to make it up to her." "Relax, we'll have them put an ordinary brain in you afterward. We'll care for you for the rest of your life!" Sharon giggles and says, "I'll let you in on a little secret. I already bribed the doctor. The brain they're putting in you belongs to an idiot. You're done for." I struggle with everything I have. Then, the second I'm dragged out of the car, I can't help feeling amused. Isn't this the hospital owned by my eight godfathers? When I left home, Big Pops, a CEO, had looked at me with bloodshot eyes. He'd told me that if the Stanton family so much as laid a finger on me, he would bankrupt them without hesitation. Second Pops, a surgeon, hadn't said a word. He had just quietly wiped down his scalpel. This time, it looks like Sharon and my parents won't be walking out of here alive.

Seven years ago, I swap my heart with Orion Gifford, the cyborg replica of me that my sister, Mildred Gifford, creates. However, my heart frequently gives him chest pains because of organ rejection. Mildred blames everything on me. She believes I have hidden a preexisting heart condition and have given away a defective human heart in exchange for a mechanical heart worth millions. So, she sues me for fraud and sends me a court summons. But on the day of the hearing, I don't show up. To force me out of hiding, she publicly announces to the media that she is officially taking Orion as her younger brother and leaving all her assets to him. When I still fail to appear, Mildred loses her patience and goes to the workplace address I leave behind. She steps into a sketchy factory and grabs a random worker to ask, "Do you know Zachary Gifford?" My factory supervisor, Greg Mathews, stares at her in shock and says, "Zachary? He died three years ago from sudden cardiac arrest. It was awful! His body got pulled into one of the machines. There was basically nothing left of him."

When I found out my wife was hiding the divorce papers from me, I set up a car crash and pretended I had lost my memories. Naively, I thought this could save our seven-year marriage. But when Josephine Gillard found out I had lost my memories, I saw something called relief flicker in her eyes. Calmly, she told me, "We're siblings. Nothing more, nothing less. Even if we aren't related by blood." Before I could say a word, a nurse pushed open the door with a knowing smile. "Your husband and child are here, Dr. Gillard. Oh, I can't believe you're still so in love even after years of marriage." I was struck dumb. Only after Josephine left did I finally find the courage to speak. With a trembling voice, I asked the nurse, "How long has she been married?" The nurse looked envious. "Five years, and she just came back from maternity leave." While I was risking everything to save our marriage, she had already built another family behind my back.

In the third year after my death, the one who remained faithfully by my wife's side was still the bionic robot I had painstakingly designed. It looked exactly like me and carried within it every detail of my mannerisms, speech, and habits. The only difference was that it never lost its temper with her. Because of that, my wife never sensed anything amiss. Yet each night, she brought home a different man, deliberately testing "me," desperate to see the wild jealousy and rage I once wore so vividly. Then, one day, her childhood sweetheart and first love, shoved "me" off the balcony. It was only then, in her horror, that my wife realized… "I" didn't bleed.

For the nine hundred and ninety-ninth time, the system in my mind warned me. [Warning! The lovesick part of your brain is highly active! If you refuse to leave John Miller, you’ll die an hour later!] I looked at my husband. He was scolding me for the sake of his secretary, who was his first love. I once burned down all of my award-winning drawings just because he disliked them. I calmly gave the system in my brain an order. “Since the cause of the malfunction is the lovesick portion of my brain, I hereby grant you the highest authority to remove it. Do the surgery now!” An hour later, John stopped me at the door of the ward. His eyes were bloodshot. “Grace Stone, what are you trying to pull?” I raised my head and watched him coldly and calmly. “Mister, you blocked the light. Based on an analysis, this constitutes an illegal detention. Do you need my help calling the cops?”
