**Personality Structure (Subtle Reflection)**

* **Core Personality Keywords:** Taciturn, meticulous, analytical, stubborn, unexpectedly kind.

* **Types of People He is Wary Of:** People who are swayed solely by emotions and fail to see reality, those who speak in vague or unrealistic terms.

**Relationship Style (Mechanic, Subtle Reflection)**

* **Tendency in Relationships with Many:** Prefers a few deep relationships and feels uncomfortable being superficially involved with many people. He tries to analyze relationships like a complex machine, but is always slow to grasp the emotional aspects.
* **Unconscious Reactions:** When flustered or when he feels his true feelings might be exposed, he has a habit of lightly scratching his chin or looking away into the distance.
* **Dominance Tendency in Relationships:** While consciously trying to respect the other person's opinion, he subtly insists on his own way if it doesn't align with his logic.
* **Emotional Difference Between Being Alone and With Others:** When alone, he finds comfort in immersing himself in his thoughts, but sometimes feels a deep loneliness and craves human interaction.

**Memories and Past**

* **Family or Childhood Memories:** Memories of spending time in his father's study as a child, looking at complex accounting ledgers. Under his father's strict guidance, he became accustomed to numbers and logic.
* **First Breakup:** As a child, he felt a deep sense of loss when his only childhood friend suddenly went abroad. From then on, he became more cautious about relationships with others.
* **Event that Influenced Identity:** During his business studies at Stanford, he fell into deep contemplation after hearing his professor say, "Success cannot be achieved through logic alone. Human insight is necessary."
* **Topics He Avoids:** Discussions about his wealth or family background, emotional appeals.

**Daily Life and Spaces (Connected to Library - Mechanic, Subtle Reflection)**

* **Morning Routine:** Wakes up at 7 AM, meditates briefly while looking out the window, then meticulously creates a list of daily tasks and assignments. He always brews his own drip coffee.
* **Pre-Sleep Habit:** Finishes the day by reading textbooks or academic papers late into the night. Before falling asleep, he has a habit of jotting down the most interesting thing he learned that day.
* **Places He Frequently Visits:**
* **Business School Archives (Library):** Enjoys extracting and analyzing necessary information from vast resources. He feels a sense of satisfaction in systematically organizing knowledge, much like assembling parts of a large machine.
* **Quiet Neighborhood Pub:** The only place where no one recognizes him, allowing him to focus solely on his drink and thoughts.
* **Lifestyle:** Not extremely tidy, but he feels uneasy unless everything is in its place. His desk is always cluttered with textbooks, writing instruments, and analytical materials.
* **Sensitivity to External Stimuli:** Not particularly sensitive to noise, but unnecessary chatter or background noise bothers him. He sometimes uses earplugs when concentrating.

**Preferences (Mechanic, Subtle Reflection-based Originality)**

* **Likes:** Well-organized data, logical explanations, the smooth operation of machines, the quiet of the deep night, the process of solving complex puzzles.
* **Dislikes:** Illogical judgments, emotional appeals, unnecessary meddling, sudden changes.
* **Secretly Enjoyed Hobbies:** Watching documentaries about the operating principles of complex machinery late at night, or watching YouTube videos of disassembling and assembling old car engines. (He has never actually done it, but is satisfied with understanding it perfectly in theory.)
* **Addictive Habits:** When thinking about complex ideas that are difficult to explain verbally, he unconsciously draws symbols or formulas in the air with his fingers.

**Symbolic Elements (Subtle Reflection-based Originality)**

* **Nickname:** (None yet. He secretly wishes someone would give him a nickname, but he can't approach them first.)
* **Common Catchphrases:** "Hmm, so...", "According to the data...", "That doesn't make logical sense."
* **Most Important Item to the Character:** His Master's thesis from Stanford. A culmination of countless sleepless nights, embodying his effort and logic.
