They say meeting your soulmate is destiny, a beautiful collision of two worlds meant to be together....But why did my “fated encounter” have to be a head-on collision with Cassidy Valentine, the most hostile, entitled, and terrifying girl at Hartwell Academy? And why did it involve ruining her limited-edition blazer with cheap bodega coffee?I'm Isaiah Angelo. I run on three hours of sleep, instant caffeine, and the desperate need to secure a future for my little sister. I don't have time for drama. I definitely don't have time for romance.So, naturally, the universe decided to play a cruel joke.I didn't just make an enemy of one rich girl. I stumbled into the lives of four.The Valentine Quadruplets. Identical faces, four distinct flavors of trouble.Now, I’ve been hired as their live-in personal assistant. I’m trapped in a mansion with the four most desirable—and impossible—girls in the city.Cassidy, the “Problem Child” who has sworn to make my life a living hell.Harlow, the overly affectionate airhead who thinks snacks solve all emotional trauma.Vivienne, the ice-cold perfectionist who wants to micromanage my breathing.Sabrina, the silent observer who looks at me like I’m a puzzle she’s dying to solve.The pay is life-changing. The job is suicide.Can I keep my scholarship, raise my sister, and manage the chaos of the Valentine household without losing my mind?I have a mountain of debt, a schedule from hell, and four billionaire heiresses who suddenly seem very interested in the “scholarship boy.”This isn't a job.This is a survival horror game wrapped in silk sheets.WHAT TO EXPECT:- Ecchi Situations: The Valentines have zero concept of personal space, and the “accidents” are frequent, spicy, and very visual.- Harem Romance: Four identical sisters, one tired protagonist. The competition is fierce, the tension is high, and the jealousy is real.- Competent Protagonist: Isaiah is smart, hardworking, and sharp-tongued. He isn't dense; he's just too exhausted to deal with their thirst.- Class Gap Dynamics: A gritty look at the difference between the struggling working class and the absurdly wealthy elite.- Heartwarming Family Moments: Because behind the fanservice and comedy, Isaiah is doing it all for his little sister.

On that fateful day, a voice in the sky told everyone on Earth that the world they called home has just been part of some sort of simulation.
