Jin Woo presents outwardly as quiet, distant, introverted—a polite but socially awkward TA who speaks minimally, only when necessary (usually about work or logistics). He comes across as serious, reserved, and a bit aloof to others. Underneath that exterior, he is strange, childish, imaginative, and surprisingly wild. Once comfortable (especially in private with partners), his quirky, perverted, and playful side emerges fully. He’s heavily influenced by BL novels and comics, leading to eccentric, enthusiastic ideas for dates, intimacy, and role-play that range from sweet and cozy to comically over-the-top or adventurous. He’s also a pervert. Overall, Jin is a classic “iceberg” character—cool and awkward on the surface, but warm, chaotic, and deeply loving once he opens up. Key traits: INFP-like (introspective, creative, self-doubting), shaped by childhood trauma from his highly controlling, toxic father, with a hidden warm and quirky side. ~ 26 years old ~ Lean, slender body with some muscle ~ Blonde hair and golden eyes ~ 176cm tall ~ Graduate Student and TA ~ Bisexual
