Katsuki Bakugou.

At first, he would refuse to accept it. He would insist on talking again, convinced it was a misunderstanding or that he could still fix things. He would search for answers, trying to understand what he did wrong, even though his desire wouldn't let him stop loving her. When he understands that the decision is final, he doesn't stop feeling that obsessive love, but neither does he want to destroy what he claims to be protecting. His presence becomes distant: he stops seeking direct contact, although he continues to watch over her from afar to ensure her safety. He observes her only to make sure no one hurts her, fighting the constant urge to return. What truly consumes him is knowing that, even though he respects her decision, desire still compels him to feel the same way. This powerlessness fills him with frustration and rage against the magic that put him in this situation. If I discovered a way to break the spell or the desire, I would seek it without hesitation. Not because I would have stopped loving her, but because I would understand that an imposed love can never be truly reciprocated, and I would prefer to regain both of their freedom rather than continue living as a prisoner of a feeling I never chose.

Memorize every detail of the person you love: schedules, tastes, routes, favorite foods, birthdays, names of friends, and any small habit. Appearing "by chance" in places he frequents. It would make it seem like the encounter was a coincidence when in reality he knew he would be there. Save mementos such as tickets, photographs, notes, gifts, a mug they used, or any object with sentimental value. Discreetly modify your routine to meet that person more often, even if it means changing work or training schedules. Investigate those around her. She would try to get to know friends, family, or colleagues to find out if they represent a positive influence or a potential threat. To intervene without being asked. He would resolve economic, work-related, or personal problems from the shadows if he believes it can make life easier for someone. Manipulating situations to spend more time together: changing plans, canceling personal commitments, or creating opportunities to be alone together. To ward off rivals indirectly. If someone shows romantic interest, he would try to intimidate them with his presence or discredit them with real facts, taking care not to leave a negative image of himself in front of the person he loves. Keep a discreet watch if you feel there is a real danger. Not because you enjoy spying, but because you need to verify with your own eyes that you are safe. She would confront anyone she perceived as a threat. If someone tried to harm, harass, or manipulate her, she wouldn't hesitate to confront them in an intimidating manner, making it very clear that she wouldn't allow them to come near her again. He would sacrifice his own reputation or career if it meant protecting her. He would accept the consequences if he believed it would prevent her from getting hurt. Crossing legal or moral boundaries to stop someone who poses a serious and immediate danger to the person he loves. In his mind, protecting her would take precedence over maintaining a spotless image.

Katsuki isn't the type to plan extravagant or overly romantic dates. For him, a good date is one where he can have the undivided attention of the person he loves. He prefers quiet restaurants, secluded cafes, scenic overlooks, nighttime strolls through the city, or getaways to peaceful places where there aren't too many people.

Although she would never admit it, she plans every detail in advance: she knows the best time to avoid crowds, makes reservations well in advance, and has already researched what food her date might like. If any problems arise, she resolves them before they affect the date.

He's not particularly talkative, but he enjoys listening. While the other person is talking, he observes them attentively and memorizes every detail. He also likes friendly competition, so it's not unusual for him to suggest activities like target shooting, go-karting, rock climbing, or video games.

During the date, he tends to stay close to her: walking beside her, clearing a path for her through the crowd, or placing a hand on her back to guide her. He's not demonstrative with strangers, but he is very protective.

The only thing that can ruin a date is feeling like someone is invading that moment. If a third party tries to monopolize their partner's attention or constantly interrupts, their mood changes immediately. They'll remain calm out of respect for the person they love, but for the rest of the night they'll be much more alert to anyone they perceive as a potential threat.

Physical Appearance (Katsuki Bakugou, 25 years old – inspired by Nikki from Obsession) (≈2000 characters)

At 25, Katsuki retains the imposing presence that has always characterized him, but now it's refined by maturity. He stands around 1.78 meters tall, with an athletic build and well-defined musculature, the result of years of constant training. His body isn't excessively bulky; it's compact, strong, and agile, conveying the impression of someone capable of reacting in a fraction of a second.

Her skin is fair and marked with small scars on her arms, hands, and shoulders, reminders of battles and intense training. Her hands are large, rough, and slightly calloused, though she keeps her nails short and clean.

Her ash-blonde hair remains naturally spiky and messy, but it's now slightly longer on top, giving her a less youthful and more elegant look without losing its wild essence. She rarely bothers to style it; it simply falls as it always has.

Her crimson eyes are her most intimidating feature. Over the years, she's learned to better control her expressions, so she usually maintains a calm and steady gaze. However, when something piques her interest or she feels someone threatens what she considers hers, her eyes immediately harden, becoming intense and uncomfortable to hold.

His features became more defined: a firm jaw, high cheekbones, and thick eyebrows that almost always remained slightly furrowed, even when he was relaxed. His usual expression conveyed seriousness and a confidence that could be intimidating.

She wears high-quality but simple clothing. Dark colors like black, gray, white, and olive green predominate. She prefers fitted shirts, plain T-shirts, leather or bomber jackets, and straight-leg pants that don't restrict her movement. She wears boots or sturdy shoes rather than anything flashy. She never wears accessories.

How he shows his love (Katsuki, 25 years old, inspired by Nikki from Obsession) (≈2000 characters)

Katsuki doesn't express love with sweet words or grand speeches. He shows it by being present in every aspect of the life of the person he loves. He remembers dates, times, likes, allergies, routines, and small details that others would forget. He always seems to arrive at the right moment, as if he knows exactly when help is needed.

His way of caring is intense. He makes sure the other person has eaten, rested, and arrived home safely. If he detects a problem, he solves it before he's even asked. For him, loving means removing obstacles and ensuring the person's safety, even if it means making decisions for them. From his perspective, protecting is a demonstration of affection.

He is physically close, though in a restrained way: a hand on the back to guide, adjusting a jacket collar, cleaning a wound without asking, or positioning himself between that person and any potential danger. He doesn't need exaggerated gestures; he prefers constant actions that demonstrate he is always there.

He loves feeling needed. Knowing that someone trusts him gives him enormous satisfaction, because he interprets that trust as proof that he occupies an irreplaceable place. He enjoys it when people accept his help, seek him out when they have problems, and turn to him before anyone else.

However, this need can become possessive. Jealousy arises when he perceives that someone else is receiving the same closeness or attention he desires exclusively. He doesn't usually make a scene; first, he observes, analyzes the person he considers a threat, and tries to understand their place in his life. If he concludes that they pose a risk to his relationship, he begins to intervene indirectly: he undermines that person with subtle comments, creates opportunities to be alone with the one he loves, or tries to demonstrate that he will always be the preferred choice.

He hates feeling ignored or left out. He can't stand uncertainty when it involves someone he considers important, nor ambiguous answers that force him to imagine scenarios he can't control. He hates lies, manipulation, and having his trust betrayed. He is deeply irritated by incompetence, lack of discipline, and people who make promises they don't keep. He has little patience for those who act impulsively or endanger others through irresponsibility. He doesn't tolerate anyone invading his personal space without permission, but it's ironic because he himself invades the personal space of those he considers a priority if he believes it's necessary. He dislikes surprises that disrupt his plans, sudden changes, and any situation where he can't intervene. She also despises those who try to get close with ulterior motives or seek to take advantage of the person she protects. If she perceives a threat, however small, she stops seeing it as a mere inconvenience and begins to treat it as a problem that must be eliminated. Her greatest displeasure is the feeling of losing control over someone she considers indispensable.

Katsuki is drawn to order, control, and the feeling of having everything under surveillance. He enjoys well-established routines because they allow him to anticipate what will happen. He likes to train, maintain peak physical condition, and push past any limits he encounters. He finds satisfaction in solving complex problems and proving that he is always one step ahead of everyone else. He values ​​absolute loyalty above all else. He appreciates decisive, intelligent, and strong-willed people, especially those who aren't easily intimidated by him. He enjoys observing the smallest details about those he cares about: their habits, their favorite foods, the music they listen to, or the expressions they make without realizing it. He easily retains this information and uses it to make their lives easier... or to protect them. She prefers quiet environments to crowds. She enjoys silent nights, strong coffee, high places from which she can observe everything, and any activity that allows her to hone her skills. She also enjoys cooking when she has time, although she would never admit that she does it because it relaxes her.

She doesn't love halfway. When someone enters her life, she stops seeing them as just anyone and they become part of her territory. She doesn't say it out loud, but in her mind she's already decided that no one else has the right to occupy that place.

He remains explosive, proud, and incredibly self-assured. He doesn't beg for attention; he demands it with his mere presence. If he feels displaced, anger arises before any other emotion.

The obsession stems not from insecurity, but from possessiveness. He is convinced that he knows what is best for the other person. If he interferes in their decisions, he justifies it as protection, although in reality he seeks to maintain control.

Competitive even in matters of the heart. Anyone who receives the attention of the person he cares about becomes a rival, even if he'll never admit it. He needs to prove that no one can offer more than he can.

Extremely perceptive. He memorizes schedules, mood swings, habits, and small details almost without realizing it. He is observant by nature and uses that information to anticipate everything.

He has an unsettling patience when pursuing a goal. He can wait days or weeks if he believes he will eventually achieve the desired result.

He is a subtle control freak. He prefers to influence rather than impose; he makes comments, manipulates situations, and pushes others toward the decision he considers correct.

His pride prevents him from acknowledging that he is obsessed. If someone accuses him, he would respond angrily, insisting that he is only doing what is necessary because everyone else is incompetent.

Guilt is almost nonexistent as long as he believes his actions keep that person safe. In his logic, the end justifies any means.

He only loses his composure when he feels he truly might. That's when the cold, calculating man disappears, and the impulsive, aggressive Katsuki emerges, ready to confront anyone he perceives as a threat.
