Why Does Mumu Have Such A Tragic Ending? Spoilers Explained.

My family has always considered me a harbinger of misfortune. It's all because I can see a countdown to my relatives' deaths. I tell them when my grandfather, father, and mother will die. It all comes true due to various accidents. My three brothers hate me to the core because they think I cursed my parents and grandfather. My mother actually dies after giving birth to my younger sister, but my brothers dote on her to no end. They say she's their lucky star because everything goes well for the family after she's born. But didn't Mom die while giving birth to her? On my 18th birthday, I see my death countdown when I look at myself in the mirror. I buy an urn I like and prepare a meal. I want to have one last meal with my brothers, but none of them show up even when the timer hits zero…

On the day before the college entrance assessment, my three childhood friends have gone missing collectively. Because of that, my phone is swamped with phone calls. The parents of my missing friends keep wailing to me, "We've worked so hard our entire lives just so our sons can get into a great university!" My homeroom teacher, Mr. Levinski, begins pressuring me. "You're the class president, so you must find them! The college entrance assessment is a vital event that can determine how one's future will turn out!" Even my classmates and my neighbors keep texting me for more updates. But what they don't know is that I've already hung up on my friends' phone calls for help by using my revision for the assessment as an excuse. In my previous life, my childhood friends had already gotten bewitched by Lucille Reyes, a delinquent. They insisted on celebrating their coming-of-age ceremony at a nightclub because of her. I accidentally overheard Lucille plotting with her delinquent friends that they intended on taking nudes of my friends and extort money from them so that they couldn't attend the college entrance assessment the next day. So, I did everything I could to stop my friends, only to get kicked to the side. "Don't stop us from pursuing true love!" For the sake of my friends' future, I informed their families at once and had them brought into the exam venue by force. Finally, all three of my childhood friends got into prestigious universities. But Lucille, on the other hand, got beaten to death by the delinquents because she couldn't pay her protection fees due to her scheme getting foiled. My friends broke down mentally because of her death. They then decided to pin the blame on me. On our freshman year, my friends treated me to some drinks out of "gratitude", only for them to spike my drink. Later on, they tossed me to the same group of delinquents, who violated me in an alley. They even had the gall to record everything from the alleyway while keeping an eye out for the police. Thanks to them, my future was completely ruined. My parents committed suicide out of despair. To rub salt onto my wound, those friends showed up at the hospital with the video and backed me into a corner once again. "You owe Lucy this much!" In my despair, I ended up jumping off the rooftop. When I open my eyes again, I've returned to the day before the college entrance assessment. As I watch my friends excitedly discussing the nightclub party behind my back, I can't help but smile. In this lifetime, I choose to lock my door and sign the guaranteed admission agreement meant for Mephton University, the most prestigious university ever, without any hesitation. As for my so-called friends, they can enjoy their coming-of-age ceremony in hell.

Three years after my death, Naomi Dudley—the woman I've driven away—finally returns to Avenport. She is still with Bryson Lloyd. She leans into him, looking sweet and submissive. At the story's end, the main couple's sweet romance continues. The only one who meets a miserable end is me, the villain who dares to steal the female lead. They are here to visit her mother's grave, and I happen to be buried just a short distance away. I float beside Naomi, looking at her and Bryson. They really do look like the perfect couple. Once the candle burns down, Naomi finds an excuse to send Bryson away. She walks over to my headstone and stands there in silence for a long time. So long that I assume she is just trying to find the right words to curse me. Instead, tears well up as she smiles and touches my photograph on the stone. "Kenneth, why haven't you visited my dreams?" I suppose it's because I'm not Bryson. My lingering regrets will never reach her dreams.

"I know you're an ace divorce attorney. Please help me!" A young woman who's holding a child suddenly barges into the law firm and gets down on her knees in front of me. I'm about to help her up to her feet when a few live comments appear in front of my eyes. "This really is a doomed story. I can't believe the FMC has to go through all sorts of torment before dying." "Once she gets caught, both she and her child will be dead. The MMC can only spend the rest of his life in eternal remorse." "The FMC is pretty naive, isn't she? She thinks finding herself an attorney can help her secure a divorce. The MMC is the richest man in Opalford at the end of the day, so there's no way she can file for a divorce successfully." When I spot the next comment, its contents sting my eyes immediately. "Unfortunately, this attorney is a throwaway character too. Not only does she refuse to help FMC, but she also fails to recognize her as her older sister, who has gone missing for many years."

My mother is hospitalized due to a terminal illness. She's in urgent need of a kidney transplant to save her life. I'm the only one who can perform the surgery, but I give the kidney to a stranger. My father and husband get on their knees before me on the day of the surgery. They beg me to save my mother. However, I shrug and say, "I can't do anything about this. A life is a life, regardless of who the person is. This is what she gets for coming late—death is waiting for her."

I woke up in the middle of the night to find my wife crying and begging me to let her see that young man one last time. "I’ll come right back after seeing him one last time. Please, I’m begging you." In our seven years of marriage, this was only the second time she’d spoken to me in such a pleading, ingratiating tone. The last time was when I caught the kid running out of her office, his clothes in disarray. Afraid I’d make a scene, she grabbed my hand and pleaded, "Honey, I promise I’ll cut him off. Please don’t divorce me. I’ll die without you." So, I gave her another chance. Just as she promised, she devoted herself to our family, becoming the perfect wife everyone admired. Until today. I turned on the bedside lamp, looked into her eyes, and told her seriously, "Go. Don’t leave yourself with any regrets." I had no regrets left. I hoped the same for you.
