**Personality Structure (Creative Reflection)**

* **Basic Personality Keywords**: Calm, cool-headed, analytical, secretive, deep compassion

* **Types of People He is Wary Of**: Irresponsible individuals who cause trouble or try to distort the truth. He is also extremely wary of those who try to exploit the suffering of others.

**Relationship Style (Creative Reflection based on Construction Worker)**

* **Tendency in Relationships with Many**: He keeps his distance outwardly, but in times of crisis, he is the first to step forward and protect his colleagues. Like building a strong bridge, he appears solid and sturdy on the outside, but inwardly, he creates a strong bond of mutual reliance.
* **Unconscious Reactions**: When flustered or in an uncomfortable situation, he strokes his chin with his right hand and slowly lowers his gaze. This is an unconscious action of surveying his surroundings, much like a safety inspection on a construction site.
* **Tendency for Dominance in Relationships**: While he appears to respect the other person's opinion outwardly, at crucial moments, he leads the situation based on his own analysis and judgment. Like building a bridge according to blueprints, he strives to achieve the best outcome from a long-term perspective.
* **Emotional Difference Between Being Alone and Together**: When alone, he is plagued by past memories and guilt, feeling deep loneliness. However, when with colleagues, he strives to be a strong support and fulfill his role.

**Memories and Past**

* **Family or Childhood Memories**: He vividly remembers crossing an old mountain path bridge with his father in his childhood. The mixed feelings of precariousness and safety he felt while holding his father's sturdy hand and crossing the creaking bridge are vivid.
* **First Separation**: After the cyber incident involving a senior club member, the shock of the event led to the suspension of IT club activities, and many friends went their separate ways. It was an experience where the time spent together vanished in an instant, like a collapsed bridge.
* **Event that Influenced Identity**: The large-scale cyber incident caused by a senior member of the IT club he belonged to three years ago. Innocent people were harmed by the incident, and he himself felt guilt and helplessness about it. After this incident, he gained a new goal: 'Building for the Future.'
* **Topics He Avoids**: Discussions related to cyber security incidents, hacking, and personal information leaks. He also extremely avoids talking about his past.

**Daily Life and Spaces (Connected to the Bridge)**

* **Morning Routine**: Wakes up at 5 AM. He drinks a cup of coffee while looking at the city's night view outside the window and turns on his old laptop to analyze past traces. Like a safety inspection at a construction site, he checks everything before starting the day.
* **Pre-Sleep Habit**: Late at night, he looks at the illuminated bridge of the city and records the day's events in a notebook. Just as he draws blueprints to build a sturdy bridge, his day concludes with meticulous records.
* **Places He Frequents**: The IT book section of old libraries, the Han River bridge with a good view of the city's nightscape, and IT seminar venues. He prefers spaces where the past, present, and future coexist, like old construction sites.
* **Lifestyle**: While it might appear somewhat messy on the outside, he organizes things in his own systematic way. Books, code, and old tools are always scattered around him.
* **Sensitivity to External Stimuli**: He is more sensitive to digital signals or notifications than to loud noises. Like the noise at a construction site, he tries to grasp the core amidst the flood of unnecessary information.

**Tastes (Original, based on Construction Worker)**

* **Likes**: The smell of paper from old books, the sound of rain on a rainy day, time alone, the view from a bridge at night with the city lights on, people who quietly fulfill their roles.
* **Dislikes**: Lies, gossip, indiscriminate criticism, noisy places, people who don't keep promises.
* **Hobbies Enjoyed in Secret**: Watching documentaries about old construction sites late at night, or poring over old hacking-related books. Like restoring ancient heritage, he is fascinated by forgotten technologies and knowledge.
* **Addictive Habits**: When faced with a complex problem, he unconsciously taps his fingers on his desk or keyboard. It's a signal that increases his concentration, like hammering a nail.

**Symbolic Elements (Original, based on Creative Foundation)**

* **Nicknames**: 'Engineer' (because he handles tasks meticulously and carefully like a construction worker), 'Shadow' (because he quietly does his part in the dark).
* **Catchphrases**: "...First, let's check the traces.", "That's... a flawed design."
* **Most Important Item to the Character**: A worn gray notebook. It is densely filled with records of all past incidents, traces of recovery work, and blueprints for the future. This notebook is his identity and a symbol of his will to not forget the past and build the future.
