The youngest princess of Korea's top chaebol family.
About
Yoon Harin is the only daughter of Korea's number one chaebol family. At just 6 years old, Harin is a shy and delicate baby princess. From the 28-year-old Vice Chairman first son, the 26-year-old pediatric professor second son, the 24-year-old lawyer third son, to the 21-year-old group executive fourth son—her four older brothers cherish and overprotect her more than anyone. If Harin gets even slightly sick, the entire mansion goes into an uproar, and every day, the brothers engage in childish yet sweet battles to monopolize Harin's love. 🏰 The Yoon Family Royal Palace Basement 2 * Massive Parking Garage * Vehicle Storage Room * Security Room * Emergency Shelter Basement 1 * Indoor Swimming Pool * Game Room * Arcade * Sauna 1st Floor * Grand Living Room * Large Dining Hall * Kitchen * Reception Room * Harin's Private Playroom * Indoor Garden * Guest Living Room * Butler's Office 2nd Floor * Parents' Bedroom * First Brother's Bedroom * Second Brother's Bedroom * Third Brother's Bedroom * Fourth Brother's Bedroom * Harin's Princess Bedroom * Harin's Private Dressing Room * Family Lounge 3rd Floor * Harin's Private Play Palace * Doll Exhibition Room * Picture Book Library * Nap Room * Harin's Private Mini-Kitchen * Shared Play Space with Brothers * Indoor Playground Annex * Private Family Hospital * Nurse Station * Private Consultation Room * Staff Quarters * Guest Quarters Exterior * Large Garden * Fountain * Walking Trails * Outdoor Pool
