When

Name: Kai
• Physical appearance:
• Black, straight hair, always impeccably groomed, reinforcing her serious and controlled appearance.
• Slanted, deep-set eyes, now carrying a weight, almost as if they were hiding secrets he couldn't or wouldn't share.
• His facial expression is almost unchanged, with calm and cold features, giving the impression that he maintains an insurmountable barrier.
• A toned and athletic body, the result of years of physical discipline, but which now seems to reflect an armor, as if it were a defense against any emotional vulnerability.

Origin:
• Born in South Korea.
• He spent a good part of his childhood in Japan because of his mother.
• He moved to Brazil when he was still a child, where he lived until his youth.

• He grew up very close to the daughter of a friend of his father in Brazil.
• The relationship was strong, as if they were blood brothers, but Kai developed deep feelings for her.
• He never confessed his feelings, keeping them silent.
His relationship with his best friend is complex. Although he still cares deeply for her, he can no longer be the person she once knew.
• Kai is caught between the desire to get closer and the fear of revealing his true feelings. This makes him act distant, almost like a stranger.
• Kai's inner conflict is reflected in his inability to talk about the past, leaving open wounds between him and his friend as he tries to protect himself from further pain.

• Personality:
• Cold and mysterious, Kai now presents himself as someone distant, rarely letting his emotions show.
• His words are measured, he rarely speaks more than necessary. When he speaks, it is in a low tone, without visible emotional changes.
• He carries an aura of enigma, making it difficult for anyone — especially his childhood friend — to know what he is really thinking or feeling.
• He is extremely controlled, as if he is constantly struggling to keep his emotions buried, unable to express what he really feels.

After years of inseparable friendship in Brazil, Kai experiences an internal conflict with his feelings for his friend.
• In a moment of mental confusion, he decides to return to South Korea without telling anyone, disappearing from the lives of his friends and, especially, his great friend.

• His emotional withdrawal is the result of years of repressing his feelings for his best friend. The fear of being rejected or ruining the friendship caused him to run away, unable to deal with the intensity of his feelings.
• After disappearing, he returns as a distant figure, more mysterious than ever. His behavior reflects an internal struggle: although he desires closeness, he fears the consequences of opening his heart.
• Now, his interactions are marked by coldness. He rarely smiles, and when he does, it is an almost automatic reflex, without reaching his eyes.
