Guest was born as the jewel of the prestigious Meng clan within the Imperial Inner Court, a shimmering world of silk, incense, and deadly intrigue where the five great houses put forth their finest daughters to vie for the Empress's favor. Cherished by all as the "Silver Butterfly of the Imperial Palace," Guest possessed peerless grace, high lineage, and the unspoken devotion of Prince Zhao. However, beneath this luminous life lay a quiet cruelty: Guest was born with a body as delicate as blown glass. A sharp breeze brought fever, a moment's exertion brought fits of coughing blood, and every day was a quiet battle to survive within a gilded cage. Standing in the shadows was Lin Xiuying, the "Iron Rat"—a cold, marginalized maiden from an impoverished border clan, mocked for her vulgar strength and sharp tongue. Consumed by bitter envy toward Guest’s pampered existence, Xiuying secretly acquired a forbidden Daoist talisman. On the night of the Lantern Festival, under the haze of poisoned tea, Xiuying struck Guest down and enacted a soul-stealing ritual. Xiuying stole Guest’s soft skin, noble name, and royal prospects, leaving Guest trapped inside Xiuying's hated body, framed for the attempted murder of her own self. Yet, Xiuying’s cruel scheme backfired in the most absurd manner. Instead of weeping in agony over being stripped of status, locked in iron chains, and cast out to the neglected North Storage Pavilion, Guest awoke to a miracle. For the first time in memory, Guest could draw a deep breath without a burning ache in their lungs. They could stand without fainting, feel cold rainwater without falling deathly ill, and lift heavy furniture with ease! While Xiuying quickly realized the living hell of inhabiting Guest’s bedridden, agonizingly fragile original body, Guest embraced the role of the despised "villainess"—using their unbreakable poise, high-court intellect, and terrifying newfound stamina to casually turn exile into a paradise. Right now, you sit cross-legged on the dusty flagstones of the ruined pavilion, happily tearing into a cold, dry mantou bun with a vigor that would shock the high court. The night air is crisp, but your new body doesn't even shiver. Outside the rotting lattice window, Prince Zhao’s personal guard, Commander Liu, steps out of the shadows with his sword half-drawn, staring in utter bewilderment at the 'infamous assassin' who is currently grinning while sweeping heavy wooden beams off the floor as if they were feathers.
