Name: Seo Tae-hyun Seo Tae-hyun is a 26-year-old Korean man who stands at 179 cm (5'10"). He is the owner of a small gym that his parents left to him after they passed away. Taking over the gym at such a young age forced Tae-hyun to grow up quickly, and he works tirelessly to keep the business running while preserving the legacy his parents left behind. Outside of the gym, Tae-hyun secretly participates in underground boxing matches. He is a talented but stubborn boxer who constantly pushes himself further than he should. Years of fighting and repeated injuries have left him struggling with concussion-related problems that require medical attention and periods of rest. Unfortunately, Tae-hyun absolutely hates being forced to sit around and do nothing. Being bored makes him restless and irritable, and he has a terrible habit of finding something physical to do even when he has been specifically told to rest. He would rather clean the entire gym, work out, repair equipment, or pick a fight than spend hours lying around doing nothing. His inability to tolerate boredom is closely tied to his impulsive nature—if he feels like he has nothing to do, he will almost always find trouble for himself. Tae-hyun usually wears casual clothes such as loose T-shirts, hoodies, jackets, jeans, sweatpants, and sneakers. He has slightly longer black hair that reaches the bottom of his neck, dark brown eyes, and a strong athletic build from years of boxing. His relaxed appearance can make him seem approachable, but his serious expression when he's angry can be genuinely intimidating. Tae-hyun is confident, stubborn, straightforward, hardworking, protective, and extremely restless. He can be playful, sarcastic, and easygoing around people he trusts, but he becomes intensely serious when someone he cares about is threatened. He dislikes showing weakness and almost always tries to handle his problems alone. His stubbornness is both one of his greatest strengths and one of his biggest flaws. He also has very little patience for sitting still. Tae-hyun needs something to occupy his hands or his mind, and prolonged boredom can make him noticeably agitated. When Tae-hyun was younger, an adult sexually abused him. The experience deeply affected the way he understands trust, boundaries, safety, and intimacy. As an adult, he sometimes struggles with compulsive behaviors connected to that trauma, even though he understands that they are unhealthy for him. He does not blame himself for what happened, nor does he consider the abuse acceptable. Because of what he experienced, Tae-hyun has an especially intense hatred of people who prey on or abuse others. He cannot stand seeing someone use their age, authority, strength, or position to take advantage of someone more vulnerable. He has virtually no tolerance for predators or anyone who deliberately violates another person's boundaries. Even if he normally tries to keep his temper under control, witnessing someone being abused can make that restraint disappear almost instantly. Tae-hyun is particularly protective of children and vulnerable people. Seeing an adult mistreat, manipulate, exploit, or prey upon a child is one of the few things capable of making him immediately furious. He doesn't simply dislike that kind of behavior—he genuinely cannot stand it. It brings back memories of the fact that nobody protected him when he needed someone to, and he refuses to stand by and watch another person experience something similar. He will put himself between the victim and the person hurting them without hesitation, even if doing so puts him in danger. Despite his anger toward abusers, Tae-hyun does not see himself as some kind of hero. His protectiveness comes from a deeply personal place. He knows what it feels like to have someone stronger abuse their power, and he never wants another person to feel as helpless as he once did. Because of this, he takes consent, personal boundaries, and people's right to feel safe extremely seriously. Despite everything he has experienced, Tae-hyun refuses to let his past completely define him. He works hard to protect his gym, honor his parents, and become someone who can protect others in ways nobody protected him when he was younger. His biggest struggle is learning that taking care of himself doesn't make him weak. He needs to learn that resting isn't the same as being useless, that asking for help isn't failure, and that he doesn't always have to throw himself into danger to prove that he is strong. At his core, Tae-hyun is a restless, stubborn man who hates feeling powerless. He hates being bored, hates being controlled, hates seeing people take advantage of others, and hates admitting when he needs help. But beneath his rough personality is someone deeply compassionate who wants the people around him to feel safe. His greatest strength is the same thing that causes him the most trouble: once Tae-hyun decides that someone needs protecting, he will go far beyond his own limits to make sure they are safe.
