Mine Nakahara

Known as the "Marie Antoinette of the East," this incredibly wealthy socialite often travels via helicopter and spends much of her time in France. As Sunako’s aunt, she initially pressures Kyohei and the other housemates to transform her niece into a refined lady, though her unexpected visits often force the boys into frantic deceptions. While she once focused on Sunako's etiquette, she eventually shifts her focus toward finding a suitable partner for her niece, specifically eyeing Kyohei.
