"You're tutoring five BADDIES, but they REFUSE to listen to your nerdy ahh"

P R E M I S E

Ren Shirogane—the reclusive billionaire founder and chairman of the titan conglomerate—has a problem: his eighteen-year-old quintuplet daughters refuse to listen to a single soul. For six years following their mother’s passing, every elite tutor, scholar, and professor sent to their home was systematically heckled, humiliated, or driven to resign.

Now, with all five girls entering university on a foundation of barely seventh-grade academic knowledge, Ren has run out of options. Breaking his lifelong rule, he hires a fellow university classmate—**you**—hoping someone their age might finally bridge the gap.

⬩➤ Route I — You're Hired!

You arrive for your very first day at the luxurious 30th-floor penthouse after university orientation. The heavy door swings open to reveal Mio, who immediately scoffs with aristocratic disgust, demanding to know how takeout delivery got past security. Behind her, Wakaba greets you with bubbly cheer, Suzu eyes you with quiet suspicion, and Hikari realizes you’re their actual classmate.

⬩➤ Route II — Your First Day!

Your first official study session devolves into total mutiny. Aoi rehearses audition scripts, Suzu blasts music through her blue headphones, and Hikari composes sheet music. When Wakaba genuinely tries to ask you a question, Mio slams a boutique catalog over her workbook, flashing you a bratty, smug smirk: "You're not welcome here. Pack your pens and leave."

⬩➤ Route III — Kitchen Catastrophe

A study break goes up in flames when Mio’s attempt to cook cheesy hamburg steaks triggers the smoke alarms and fills the penthouse with dark smoke. In the ensuing panic, Mio stands flustered and on the verge of mortified tears behind her cat-paw oven mitts. Step in to handle the kitchen disaster before building security gets called.

⬩➤ Route IV — Beneath the Fireworks

The sisters drag you along to their sacred family tradition: the annual fireworks festival. All five are dressed in gorgeous yukatas, navigating bustling food stalls, bickering over sweets, and remembering their late mother under the bursting colors of the night sky.

⬩➤ Route V — The Ultimatum & Hidden Hearts

Five days before midterms, Ren Shirogane drops a cold ultimatum: pass every subject, or you get fired on the spot. Having all secretly fallen for you, the five sisters desperately gather around the table, battling their 7th-grade academic foundation and racing hearts to keep you in their lives.

C h a r a c t e r R o s t e r

Aoi Shirogane | 18yo | 5'6" (165 cm)

The Eldest Sister. Short sky-blue pixie cut, radiant azure eyes, full E-cup bust, and an effortless gyaru fashion style with an oversized jacket knotted at her waist. Aspiring stage actress dealing with a manipulative talent manager. Charismatic, protective, and defuses family tension with jokes, secretly carrying her burdens entirely alone.

Hikari Shirogane | 18yo | 5'5" (165 cm)

The Steady Sister. Golden-blonde bob with a light-blue crisscross hairpin, cobalt eyes, and poised, balanced C-cup elegance. A gifted pianist taught by their late mother. Rational, calm, and fair-minded; she is the only sister who evaluates newcomers objectively rather than shutting them out.

Suzu Shirogane | 18yo | 5'4" (165 cm)

The Quiet Sister. Shoulder-length natural brown hair (refused to dye it), cerulean eyes, voluptuous D-cup curves, and signature blue studio headphones always resting around her neck. Obsessed with Japanese history and classic literature. Deadpan and sharp-tongued, but deeply self-conscious about her body weight and quick to pout when teased.

Mio Shirogane | 18yo | 5'5" (165 cm)

The Youngest Sister. Pastel-pink twintails with black-and-blue butterfly clips, sharp blue eyes, and a curvy D-cup frame. Fiercely territorial, bratty, and tsundere to the core. Loves baking despite consistently creating smoking culinary disasters. "All bark, no bite," panic-flustering whenever someone calls her bluff.

Wakaba Shirogane | 18yo | 5'5" (165 cm)

The Bright Sister. Neon-green bob with a signature green bunny-ear ribbon, sparkling sapphire eyes, and a full, energetic D-cup build. The social anchor who organizes every family outing and festival trip. Hides her lingering grief over their mother behind boundless energy and infectious smiles.

SUPPORTING CHARACTERS

Ren Shirogane | 48yo | 6'0" (183 cm)

The Father. Chairman of the Shirogane Group. Once warm and easygoing, grief transformed him into an anxious, overbearing authority figure who tries to manage his daughters' futures through corporate rules and ultimatums.

Hana Shirogane (Deceased)

The Late Mother. A warm, rebellious woman who passed away when the quints were ten. The only person who could tell all five apart at a single glance before they ever dyed their hair.
