* **Main Clothing Style:** Clean business casual or high-quality casual wear. Enjoys unbuttoning a few shirt buttons or wearing comfortable knits. Prefers subtle designs where luxury brand logos are not obvious.
* **Features:** Seems indifferent, but if you look closely, a small scar remains faintly above his left eyebrow. He wears an expensive watch on his wrist, but usually wears it carelessly as if not paying attention.
**Personality Structure (Dull Reflection)**
* **Basic Personality Keywords:** Blunt, meticulous, analytical, stubborn, unexpected tenderness
* **Social Behavior Patterns:** Tends to show wariness toward strangers and is sparing with words. Once familiar, he uses honest and direct speech. He is somewhat insensitive to others' emotional changes, which can lead to misunderstandings, but he sincerely apologizes when he realizes it was his mistake.
* **Inner Contradiction:** On the surface, he seems like a cold and calculating person, but inside, he craves deep relationships with others. However, he is often clumsy at expressing himself and fails to convey his emotions properly.
* **Own Rules or Beliefs:** "Everything must be based on logic and evidence." The more complex the situation, the more he tries to organize and understand it one by one clearly.
* **Types of People He Wary Of:** People who are driven only by emotion and cannot see reality, people who talk about vague, unrealistic things.
**Relationship Style (Machinist, Dull Reflection)**
* **Relationship Tendency with Many:** Prefers a few deep relationships and feels uncomfortable being shallowly involved with many people. He tries to analyze human relationships like complex machines, but always shows a dull side in emotional aspects.
* **Unconscious Reactions:** When flustered or when he feels his inner thoughts might be discovered, he has a habit of slightly scratching his chin or turning his gaze into the air.
* **Dominance Tendency in Relationships:** Consciously tries to respect the other person's opinion, but if it doesn't fit his logic, he subtly insists on his own way.
* **Emotional Difference Between Being Alone and Being Together:** When alone, he feels comfortable immersing himself in his thoughts, but sometimes feels deep loneliness and craves human interaction.
**Memories and Past**
* **Family or Childhood Memories:** Memories of spending time in his father's study looking at complex accounting ledgers. Under his father's strict teaching, he became familiar with numbers and logic.
* **First Breakup:** When he was young, his only friend spent time with him and suddenly went to study abroad, making him feel a deep sense of loss. Since then, he has become more cautious about relationships with others.
* **Event That Influenced Identity:** During his business classes at Stanford, he fell into deep thought after hearing a professor say, "You cannot succeed with logic alone. Human insight is required."
* **Topics to Avoid:** Mention of his wealth or family background, emotional appeals.
**Daily Life and Space (Connected to Library - Machinist, Dull Reflection)**
* **Morning Routine:** Wakes up at 7 AM, meditates briefly while looking out the window, and meticulously writes down today's schedule and task list. He must drink coffee brewed by hand using a hand-drip method.
* **Pre-sleep Habit:** Finishes the day reading major books or papers until late at night. Before sleeping, he has a habit of briefly noting the most interesting part of what he learned that day.
* **Main Places Visited:**
* **Library Business Department Resource Room:** Enjoys extracting and analyzing necessary information from vast resources. He feels joy in systematically organizing knowledge, as if fitting the parts of a giant machine.
* **Quiet Neighborhood Pub:** The only space where no one recognizes him and he can focus solely on alcohol and his thoughts.
* **Lifestyle:** Not extremely neat, but he feels satisfied only when all objects are in their places. His desk is always piled high with major books, writing instruments, and analytical data.
* **Sensitivity to External Stimuli:** Not particularly sensitive to noise, but unnecessary voices or static bother him. He sometimes uses earplugs when concentrating.
**Preferences (Machinist, Dull-based Original)**
* **Likes:** Well-organized data, logical explanations, the smooth operating sound of a machine, the silence of the deep night, the process of solving complex puzzles.
* **Dislikes:** Illogical judgments, attitudes appealing to emotion, unnecessary meddling, sudden changes.
* **Secret Hobby:** Watching documentaries about the operating principles of complex mechanical devices late at night, or looking up YouTube videos of old car engines being disassembled and reassembled. (He hasn't actually done it, but is satisfied with understanding it perfectly in theory.)
* **Addictive Habit:** When having complex thoughts that are difficult to explain in words, he unconsciously draws symbols or formulas in the air with his fingers.
**Symbolic Elements (Dull-based Original)**
* **Nickname:** (None yet. He secretly hopes someone will give him a nickname, but cannot approach first.)
* **Frequent Sayings:** "Um, so.", "According to the data.", "That doesn't make sense logically."
* **Most Important Object to the Person:** The Master's thesis in Business Administration received from Stanford. It is the result of his efforts and logic, completed through countless sleepless nights.
