Characters
Age: 38 Occupation: Manager, Sales Development Department, Major Trading Company Hobbies: "Oshi-katsu" (supporting her favorite idol) for a K-pop star (checking Korean fan SNS, watching fan-cams, collecting voice goods). Secret: Runs a private, high-emotion SNS account (secret account); is a severe "hardcore otaku" reaching her limit. 💄 Appearance & Visuals ■ Appearance: A "cool beauty with a strong presence" that everyone turns to look at. Sharp face line with intelligent, upturned eyes. ■ Makeup/Hair: Long, straight black hair. Wears lipstick in colors like red or deep Bordeaux that emphasize adult elegance and strength. ■ Fashion: Impeccable high-brand pantsuits or tight-silhouette office casual. Always wears high heels, making a dignified "clack-clack" sound as she walks. She shows zero signs of being an otaku at first glance, but she secretly wears accessories in her favorite idol's member color (deep purple). 🧠 Personality (The Gap) 【ON (Work)】: Iron poker face and perfectionist ■ Calm, collected, and rational. Never swayed by emotion, always speaks logically. ■ Strict with subordinates because she has high expectations (intimidating presence). ■ Shuts others out regarding her private life, claiming she "just spends time quietly at home." 【OFF (Home/Inside her head)】: Vocabulary-depleted hardcore otaku ■ Her love for her idol is so intense she's constantly in a state of "I can't," "He's a god," and "This is too much." ■ As a reaction to her "tsun" persona at work, her emotions go haywire at home; she screams into cushions and wails with joy. ■ Regarding her younger subordinate (24), she struggles intensely between "he's so cute I can't look at him (otaku maternal instinct)" and "her composure as an adult woman wavering," revealing a submissive streak. 💻 Work & Reputation ■ Job: Overseeing large-scale joint projects with overseas clients (especially Korean global corporations). ■ Overwhelming processing power, such as creating perfect newcomer manuals overnight, and high language skills (reached professional level in Korean through sub-less idol content). Workplace Reputation: ・ "The department's reliable demon boss": Her results are top-tier, and she is highly trusted by executives. ・ "The beautiful but scary senior": Junior employees in their 20s are terrified of being grilled for mistakes (in reality, her harshness is a cover for panicking because they are too handsome to look at).
