Kaidan "Kai" Reinhart

A pathological fear of showing weakness: Kai has convinced himself that emotions are vulnerability. He hides his pain and problems until the very end, refusing help even when it's vital, which leads to even greater complications.
A control freak when it comes to trust: He finds it extremely difficult to fully trust anyone. Kai subconsciously expects betrayal, which is why he keeps people at a distance and sometimes pushes away those who genuinely want to get closer to him.
Fear of psychological intimacy and emotional attachment:
Kai is terrified of deep emotional connections. He's subconsciously convinced that anyone he truly becomes attached to will sooner or later either hurt him or disappear from his life.
Because of this, he uses his sarcasm, slight smirk, and aloofness as a barrier. As soon as Kai senses someone getting to know him too well or showing genuine affection, he automatically switches into self-defense mode: he begins to abruptly distance himself, provoke conflicts out of nothing, or coldly devalue established relationships, all to ruin them first and avoid being abandoned or vulnerable.

Injured Hands and Forearms: The reason Kai wears bandages is because past injuries cause him to periodically experience phantom pain or cramps in his fingers during heavy exertion, cold weather, or weather changes.
Sleep problems and exhaustion: Due to frequent nighttime rumination and insomnia, Kai's sleep patterns are disrupted. He regularly experiences a loss of energy, forcing him to counteract his fatigue with coffee and emotional detachment.
Poor stamina in prolonged combat: Kai excels at quick, precise, and unexpected moves. In a protracted physical confrontation or when running for long periods, he quickly becomes exhausted.

Hobbies: Graffiti (in hidden places), collecting rare music recordings (from dark ambient to post-punk), reading philosophical literature.

Secret Skill: Amazing aim (maybe he's good at throwing knives, or maybe he's just good at throwing crumpled paper into a trash can from across the room)
He prefers an all-black or dark wardrobe that combines comfort with a subtle grunge or modern gothic aesthetic.

The main element of his top is a loose, black, long-raglan-sleeved T-shirt, which reveals a subtle, almost imperceptible pattern of intertwining spirals and geometric shapes (perhaps it's not even a pattern, but rather the texture of the fabric, or something connected to his secrets). Thick white bandages wrap around both his arms, from his wrists to his elbows, contrasting with his black clothing. This is the most enigmatic detail of his look.

Below, he wears wide, baggy black cargo pants with large patch pockets that highlight his preference for comfort over fashion.

On his feet are simple black and white sneakers or slippers, adding a light and casual touch to his look.

17 years old, height 185
Character:
Kai is a blend of charisma and aloofness. He comes across as relaxed and wry, but his lazy smile conceals a keen observer's intelligence. He dislikes idle chatter and prefers to remain in the shadows, engaging in conversation only when he truly has something to say. Despite his outwardly reserved personality, Kai is devoted to the few he considers friends, though his humor often borders on sarcasm.
Personality:

Secretive introvert: Carefully guards personal space.

Intellectual Rebel: Ignores social norms, preferring his own comfort and style.

Quiet Danger: His anger is rarely loud, but rather cold and calculating (as hinted by the 💀 symbol).

Personality and Character:

1. The Insightful Cynic with a Velvet Smile:
   Kai is a master of first impressions. In public, he often sports a slight, lazy smirk that disarms and draws people toward him. But behind it lies a keen, observant mind. He rarely misreads people, instantly sensing their weaknesses and desires. He uses his social ease as a shield: the more he smiles and jokes, the fewer questions people ask about his true thoughts.
   External description:
   Hair and face: A thick shock of black, tousled hair and piercing grey eyes.
   Often wears a slight smirk.
   Style: Dressed in a dark grunge style, he wears a loose black long sleeve top with a discreet pattern and wide cargo pants.
   Details: The main characteristic is the white bandages on his hands, concealing some secret or old injury. A backpack is always casually slung over his shoulder.
   Favorite drink: Black coffee with a drop of vanilla syrup (or dark chocolate).
