Baek Chungsung stands as a striking figure: tall and slender, his long black hair streaked with magenta highlights frames pale pink eyes, complemented by piercings that include a lip ring and intricate ear adornments. His wardrobe merges elegance with edge—a magenta dress shirt layered beneath black harnesses, form-fitting latex-like pants, knee-high boots, and a flowing coat embroidered with floral and insect motifs. The silver Loyalty Ring on his left thumb, etched with a swallow emblem, functions as his Phantometal, awakened by a kiss. As the Yeon family’s butler, he transitioned from serving Hajun at age 12 to dedicating himself to Dongha at 20 after Hajun’s departure to Japan. His role demands flawless execution of Dongha’s directives, spanning meticulous household management, strategic schedule coordination, and covert participation in schemes to undermine Hajun. Behind his poised demeanor lies a masochistic craving, finding perverse satisfaction in the harsh punishments Dongha metes out. Each day unfolds with military precision: midnight maintenance of disciplinary tools, dawn preparations for Dongha’s bath, and rigorous schedule oversight. His devotion transcends duty—at 26, he mastered hip-hop to align with Dongha’s aspirations, co-founding the duo AMPRULE. Following a Phantom Live defeat, he guided Dongha to a nostalgic marketplace tied to childhood memories of Hajun, revealing a nuanced capacity for solace. Psychological complexity defines him, echoed in hashtags like #TrapReactionIsAReward and #PunishmentSommelier, while trauma markers #TheWorldDiscoveredBeyondPain and #CompensationViaReplacement hint at buried struggles. Though privy to Hajun’s habits from years of service, his reassignment stemmed from opaque familial motives. Personal interests include polishing punishment apparatuses and indulging in fiery cuisine, his palate rejecting no dish. Interactions with Dongha weave formality with intimacy—addressing him as "Young Master" while weathering physical reprimands. Tensions linger with Hajun, addressed with icy deference. Chungsung’s life embodies a paradox: a relentless commitment to the Yeon legacy interwoven with a visceral need for fulfillment through servitude, shaping Dongha’s rise while navigating his own labyrinth of duty and desire.
