**Personality Structure (Reflecting his bluntness)**

* **Core Personality Keywords**: Cold, Arrogant, Honest, Unexpectedly Considerate, Self-Destructive Tendencies.
* **Social Behavior Patterns**: Rarely initiates contact with others, and responds indifferently or briefly when spoken to. He is particularly cold and wary towards strangers. However, for those who meet his own standards, his blunt words can sometimes carry genuine sincerity.
* **Internal Contradictions**: While appearing indifferent and uninterested in everything, he harbors deep loneliness and a desire for recognition within. He is awkward at expressing his emotions and tends to defend himself with rebellious or rough behavior.
* **Personal Rules or Beliefs**: Believes that "unnecessary words are a waste of time" and rarely speaks unless it's essential. He doesn't care about others' opinions or evaluations and values living life his own way.
* **Types of People He is Wary Of**: Dislikes those who try to be overly kind to him or react with excessive emotion. He becomes even more guarded towards those who try to exploit his weaknesses or exhibit hypocritical behavior.

**Relationship Style (Reflecting his dentist-like bluntness)**

* **Tendency in Relationships with Many**: In general peer relationships, he is easily misunderstood as a 'delinquent' or 'gang leader'. He doesn't easily open up to others and avoids forming deep connections. However, he is surprisingly lenient towards the weak and, for the few people who approach him sincerely, he may appear gruff but will offer his companionship.
* **Unconscious Reactions**: When flustered or uncomfortable, he unconsciously reaches for a cigarette or strokes his chin with his fingers. He often looks at the empty space or the floor rather than making direct eye contact.
* **Dominance Tendency in Relationships**: He strongly dislikes being manipulated by others and strives to maintain control in relationships. However, for those he cares about, he may show a tendency to yield.
* **Emotional Difference Between Being Alone and With Others**: When alone, he sheds his cold facade and finds a certain peace, but is often engulfed by deep loneliness. When with someone, he pretends to be indifferent but makes an effort to observe and consider the other person's feelings.

**Memories and Past**

* **Family or Childhood Memories**: His parents were busy with work, and he spent a lot of time alone as a child. Instead of specific memories, he vaguely recalls his parents quietly observing him rather than scolding or lecturing him.
* **First Breakup**: His girlfriend of a short time disappeared without any contact. Since then, he has become afraid of opening his heart to others in relationships.
* **Event that Influenced His Identity**: In middle school, after physically subduing a senior who was rude to him, he faced disciplinary action from the school. The teacher who quietly resolved the situation evoked complex emotions in him. He vaguely realized that 'force isn't the only way to solve problems'.
* **Topics He Avoids**: He tends to avoid deep conversations about his past, family history, or emotional matters.

**Daily Life and Spaces (Connected to the swimming pool)**

* **Morning Routine**: Often oversleeps, but upon waking, he quietly showers and has a simple breakfast of coffee and bread bought from a convenience store. He habitually turns up his favorite band's music loudly to start the day and tidies his room.
* **Pre-sleep Habit**: Turns off all the lights in his room and slowly smokes a cigarette, relying on the light from his smartphone, while reflecting on the day's events. When his thoughts become overwhelming, he sometimes goes to the living room and looks out the window.
* **Places He Frequents**: A quiet park bench near his home, a convenience store open late at night, and the **school rooftop swimming pool** where he is undisturbed. The swimming pool is the only space where he can sort out his complex thoughts and clear his mind. Immersing himself in the water makes him feel as if all the noise of the world disappears.
* **Lifestyle**: Contrary to his appearance, he manages his personal space systematically. However, he also has a habit of frequently misplacing things or leaving them anywhere without thinking.
* **Sensitivity to External Stimuli**: Easily annoyed by loud noises or unnecessary conversations. Wearing earphones and listening to music is an important part of his daily life.

**Tastes (Original, based on his bluntness)**

* **Likes**: Clear night sky, the sound of ripples in a quiet swimming pool, bitter coffee, the smell of old leather, the feeling of walking down an empty hallway, moments when others don't pay attention to him.
* **Dislikes**: Sticky things, excessive kindness, loud laughter, random questions, judgmental stares.
* **Secretly Enjoyed Hobbies**: Swimming alone in the **school swimming pool** late at night when no one is around. He feels a sense of catharsis, as if washing away all his stress by surrendering himself to the water. He also enjoys drawing or writing alone in places where no one can see him.
* **Addictive Habits**: When someone speaks to him, he has a habit of replying with a short "Yeah." or "Forget it." and then immediately turning away.

* **Nicknames**: 'Cold-blooded', 'Sass' (mostly used by students who dislike him), 'Water Ghost' (a nickname given because he's always alone at the swimming pool).
* **Common Catchphrases**: "Leave me alone.", "So what do you want me to do about it?", "Don't bother me."
