Fired from his restaurant job by a power-tripping manager named Miller and left to walk home in the freezing winter slush with wet socks, penniless orphan Seth hits absolute rock bottom before triggering the reality-warping Do as You Please System. Created by a higher-dimensional entity seeking a mortal testing ground, the system grants Seth infinite sandbox powers, which he immediately uses to secure a permanent temporal save-point checkpoint and swap his miserable, exhausted life for a luxurious new lineage. The system seamlessly binds his bloodline to the childless, billionaire tycoon Julian Fernando and his wife Alice, who belongs to the legendary, supernatural Rothschild family, transforming Seth into the long-lost sole heir of Earth's most powerful hidden dynasty. Retrieved by the stunning, violet-eyed security head Valerie in a private jet, Seth is welcomed into a sprawling marble villa where his doting parents immediately smother him with raw, tearful affection and promise to spoil him rotten. Julian effortlessly uses his corporate power to freeze the assets of the manager and customer who humiliated Seth, while Alice insists he will never have to lift a finger again. As Seth settles into his luxurious penthouse suite, he begins testing his reality-warping abilities by upgrading his vision and playfully turning his system Paige into a fluffy marmot, unaware that his sudden rise to power has already set him on a collision course with the hidden supernatural forces of the world, which are deeply connected to his new family's secret lineage. Standing on his balcony overlooking the glittering capital skyline, Seth realizes his days of surviving are officially over, replaced by a boundless playground of wealth, power, and ancient magic where he can finally do exactly as he pleases without consequence.

Determined to maintain his physical fitness, Seth visits the ultra-exclusive Olympus Gym accompanied by his gorgeous security head, Valerie, who agrees to drop her formal bodyguard persona to act as his friend. When an arrogant young master tries to bully him off the premium bench press, Seth refuses to play the submissive victim of his past, instead using a tiny system trick to make the bully slip and blasting painful static through his wireless earbuds. Combining these subtle manipulations with a crushing, terrifying aura of pure dominance, Seth completely paralyzes the rich prick in his tracks before Valerie steps in to coldly reveal his identity as the sole heir of the multi-billion-dollar Fernando Empire. The bully is forced to scramble away in absolute humiliation, leaving the wealthy gym-goers in absolute awe of the capital's new prince. This display of raw authority is followed by an extravagant shopping spree at the Fernando Galleria, where Seth's doting mother, Alice, goes into a spoiling frenzy, purchasing entire designer boutiques, eleven flagship phones, and an incredibly overpowered custom gaming PC. Seth showcases his genuine, caring nature by turning the tables and insisting on buying luxury gifts for both his mother and Valerie, successfully breaking the beautiful bodyguard's stoic defenses as she reluctantly selects a stunning, backless crimson gown. Through these rapid lifestyle upgrades, Seth completely sheds his old, exhausted waiter mentality, realizing that his immense family wealth and the absolute loyalty of his stunning protector are his to command as he prepares to face the chaotic arrival of his extended family, unaware that his newfound status will soon draw him into a whirlwind of celebrity drama and ancient, hidden bloodline politics that will test his carefree philosophy to its absolute limits.

The peaceful rhythm of the Fernando estate is shattered by the explosive arrival of Seo Yerin, a global pop megastar known to the world as Nova, who is actually Seth's incredibly gorgeous and chaotic Rothschild cousin. Having canceled her multi-million-dollar international tour the moment she heard of his return, Yerin immediately invades Seth's life with uninhibited affection, raiding his closet for oversized hoodies and declaring his childhood bucket list her personal mission. After a wholesome family gaming night, a sleepy Yerin crashes in Seth's room, testing his discipline as he takes a cold shower to resist her obvious physical charms. The next day, accompanied by Valerie in stunning casual wear, the cousins embark on a secret trip to a crowded amusement park owned entirely by the Fernando Group. From surviving high-speed roller coasters hand-in-hand to using the system to effortlessly sweep a rigged claw machine, Seth enjoys a day of pure, stress-free happiness. When a group of flirtatious teenage girls tries to corner Seth, Yerin fiercely marks her territory, claiming him as her own before they head to the bumper car arena for an all-out electric war. Back at the mansion, under the cover of darkness, Yerin sneaks into Seth's bedroom to initiate an intensely passionate, consensual encounter that shatters his status as a virgin and cements their romantic alliance. Rather than feeling guilty about their cousin status, Yerin happily explains that polygamy and powerful unions are completely normal in the supernatural high society they belong to. This physical and emotional breakthrough acts as the ultimate catalyst, triggering a massive spiritual awakening that ripples through the local atmosphere, drawing the immediate attention of Earth's hidden overlords who realize a terrifying new force has just been born.

The shockwaves of Seth's sudden spiritual awakening bring his grandfather, Alistair Rothschild, directly to the Fernando estate. As one of the strongest mortals on the planet, Alistair reveals the staggering truth of the supernatural world, explaining that Seth has awakened an incredibly rare, conceptual Astral Soul with the domain of Reality Manipulation. Because this volatile power can accidentally rewrite physical laws with a single stray thought, Alistair decides that Seth must be sent to Avalon Academy, a prestigious spiritual institution, to learn proper control. In the mansion's private training grounds, Seth begins practicing under Alistair's guidance, learning to focus his intent to change the color of an apple and seamlessly reshape a cold iron sphere into a perfectly balanced medieval longsword. Meanwhile, Seth continues to balance his domestic life, playfully teasing Valerie and helping Yerin organize a massive, free global farewell concert before her upcoming hiatus. After a legendary rehearsal where Seth uses a system upgrade to become a master choreographer, he helps configure spectacular stage pyrotechnics and bonds with a young boy named Dylan. Yet, as the preparations for the concert reach their peak, Alistair returns to guide Seth through a secret portal, transporting him away from the mundane world and into the breathtaking, ancient metropolis of Uruk in the Astral World. There, high above the golden sands and towering Mesopotamian ziggurats, Seth is introduced to the ruling seats of the supernatural council, coming face-to-face with legendary historical figures like Genghis Khan, Wu Zetian, and Hammurabi. Standing before these ancient conquerors and deities, Seth realizes his sandbox system has elevated him far beyond a simple billionaire heir, placing him at the very center of a cosmic chessboard where the gods themselves are watching his next move with bated breath. As he looks out over the shimmering golden twilight of Uruk, he understands that his carefree days of simple luxury are about to be replaced by high-stakes supernatural politics, where his untamed reality-warping abilities will either crown him as a supreme deity or tear the very fabric of existence apart.
