Why Did The Protagonist Disappear In 'Notes On Your Sudden Disappearance'?

Just three days after we got engaged, I stumbled across a private story posted by the girl he had grown up with. 'Too bad the boy who confessed to me ninety-nine times is marrying someone else in ten days.' In the photo, he trailed behind her through a crowded mall, his arms loaded with shopping bags, looking as if he had rehearsed the scene a hundred times. Curious, I scrolled down to read the comments. 'No way. The childhood-best-friend and first-love storyline still lost? Girl, that hurts.' 'Lost? He's getting married and still spending the whole day shopping with her. She didn't lose anything.' 'I feel bad for the bride. I'm seriously waiting for confession number one hundred to happen at the wedding, followed by a runaway groom scene.' Watching strangers bicker in the comments, I quietly pressed the like button, blending into their chaos. None of them knew that in just ten days, I would be the one stepping away from the altar. The fake-death package I'd ordered was already in motion. While my fiance and his childhood sweetheart mourned the love they claimed was out of reach, I quietly counted down the days until I could disappear for good.

The moment I decided to leave Vincent Graves, I did three things. First, I recalled the pregnancy report I had been about to forward to him and replaced it with a scheduled breakup message. Second, I called the bridal boutique and cancelled the custom order for my wedding dress. I had been measured three times for it. I had waited five months. I never wore it. I never would. Third, I called Dr. Helena Shaw and accepted the invitation I had turned down a week ago. An eight-year medical research program. Completely sealed. No contact with the outside world. Before he could spring the proposal he had been planning, I vanished from his life completely. He never noticed that while he let Cora take my place at the wedding rehearsal and stayed out all night, I was quietly erasing every trace of myself, step by step. I became exactly the wife Vincent always said he wanted: reasonable, gracious, unbothered. But after I was gone, he lost control and asked me, "Why aren't you angry? Don't you love me anymore?" I said nothing. I only remembered the flirtatious voice messages Cora had sent him, the ones I had heard from his phone. And I calmly dialed the number that would take me away.

During a thunderstorm on the border, my fiancee, Eleanor Ashby, covers my retreat and falls down a cliff. The search and rescue team spends three months searching through flash floods without finding a trace of her. Everyone concludes she's dead. I refuse to give up and spend another two years looking for her. Eventually, I find her at a small clinic in a remote mountain village. But she's become the wife of the clinic's caregiver, Dylan Foster. That's when I learn she's lost her memory and fallen in love with someone else. In my previous life, I ignore her wishes and force a renowned neurosurgeon to use a high-risk treatment to restore her memories. The day her memories return, the man who has cared for and protected her for the past two years throws himself into the river in despair. Later, during an earthquake rescue mission, Eleanor and I are trapped beneath a collapsed mountainside. There's only one narrow escape route wide enough for one person. She forcibly pushes me out. Moments later, a second collapse buries her beneath a massive boulder. With her dying breath, she reaches through a crack in the rocks and grips my hand. She says in a hoarse voice, "Callum Pierce, these ten years we've spent together is repayment for the debt I owed you from the ten years before. We're even now. Neither of us owes the other anything anymore. "If there's a next life, don't let me remember the past. Please... let me be with him." Tears blur my vision. When I open my eyes again, I'm back on the day I find Eleanor. This time, I choose to respect her decision and let go of the life she's forgotten.

Three years after my wife's and daughter's deaths, they came back from the dead. Turns out, my wife hadn't died at all. She'd faked it and married the son of the richest man in Notingdun City. Ever since then, she'd stepped into the glamorous life of a wealthy socialite. When I uncovered the truth, the shock hit me like a bolt of lightning. I confronted her face-to-face. She didn't even flinch. Instead, she sneered, "You think a penniless man like you deserves to be my husband? I've remarried and taken on a new identity. Stay out of my life, or don't blame me for what happens next." Her words cut deep. Even our daughter turned her back on me. Crushed, I let go for good. But not long after, she came back regretful and begged me to remember the vows we made on our wedding day: to never leave, never forsake. I looked at her and laughed coldly. "Yes, I did make that promise once. But sadly, my wife died three years ago."

On my eighth birthday, I begged my mom to video call my dad, who was supposedly working late. The moment the call connected, a version of him from ten years in the future appeared on the screen. My mom held me close and smiled, asking him, "Ten years from now… our Lily has grown up. Was her coming-of-age ceremony a big celebration?" Dad replied coldly, "She kept trying to one-up Sarah's kid, so I sent her abroad. Too bad her luck ran out—her plane went down." My mom's face went pale. On the other end, my dad let out an icy laugh. "Claire, back then, you lied to me. You said if your 'plan' didn't work out, you'd die. I believed you. I gave up Sarah and her child to marry you." My mom's body started trembling. I reached out toward the screen. "Daddy, when are you coming home to celebrate my birthday with me?" Dad sighed and looked at her calmly. "The truth is, I wasn't working late that night. I was celebrating Sarah's daughter's birthday. Now you know everything. What you do next is up to you." Suddenly, a cold robotic voice echoed in my ear: [Host, do you choose to abandon the original world and stay here forever?] I wiped the tears off my mom's face and, barely understanding what was happening, said, "Mommy, does that mean Daddy doesn't want us anymore? Then let's not want him either. Okay?"

I was the side character, the one destined to be neglected, forgotten, and never chosen. In the novel’s story, I was merely a background existence—the woman fated to marry the male lead, yet never once receive his love. The wife who shared his name but never his attention. Salvatore Mancini. The perfect male lead. Cold, powerful, and admired by everyone. Except me. Because in this story, his heart already belonged to someone else. When I first realized I had transmigrated into this novel, I thought I could change my fate. I tried to avoid the original scenes, tried to step away from the plot. But every time I tried to change something…I returned to the same place. The same moment, the same outcome. As if the unseen author of this story was reminding me again and again: You are only a puppet, and puppets don’t decide their roles. So I stopped resisting. If the story wanted me to be the neglected wife, then I would simply live quietly and let the plot run its course. That was my plan. Until one night, when I finally looked at the man and said casually— “Tell me something, Mr. Mancini. Aren’t you supposed to be my husband?” His cold eyes narrowed slightly, but I simply leaned back and smiled. “Then fulfill your role properly. Let’s see… what kind of man the great Salvatore Mancini is.” For the first time since our marriage he actually looked at me, not through me. At me. I didn’t know what changed after that, but from that night onward. Even when he looked at me with clear irritation. Salvatore Mancini began appearing around me more and more. Which left me with a very unsettling thought. The plot…It didn’t change, right?
