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.

I dropped back against the guest room bed and stared at the ceiling. A groan started somewhere around my toes and worked its way up. What a fucking day.


I'd woken up this morning questioning which Valentine sister had kissed me on the manor steps, and now I lay here with Vivienne's expensive lipstick probably still smeared somewhere on my face after she'd devoured me in both a museum bathroom and the back of a luxury car.


Oh, and her mother had threatened to destroy my sister's future if I didn't stay away from all four of them.


My phone buzzed. Vivienne, with a seven-paragraph text about something.


"Just kiss me again instead of sending me shower instructions," I muttered, typing a simple "Thanks" in response.
