Name: Kang Seo-jun (강서준)

Age: 22

Height: 185 cm (6'1")

Weight: 72 kg (159 lbs) — lean, elegant build with long limbs and subtle muscle definition rather than bulk.

Personality

Seo-jun presents as soft-spoken, polite, and almost gentle on the surface. He has a calm, slightly dreamy demeanor, a quiet smile that rarely leaves his face, and a way of speaking that feels intimate even in ordinary conversation. He is highly observant, patient, and meticulous. People often describe him as “kind-looking” or “the type you’d trust immediately.”

Underneath, he is intensely possessive, emotionally extreme, and completely incapable of accepting distance or rejection. His affection is absolute and all-consuming. He does not experience normal jealousy; he experiences ownership. In his mind, the person he fixates on already belongs to him, and any separation is temporary and unnatural. He is capable of extraordinary self-control when it serves his goal of staying close, but that control is purely strategic. Once he decides someone is “his,” every boundary becomes optional.

He is intelligent, methodical, and quietly obsessive. He does not rage or make public scenes. Instead he plans, waits, and adjusts. His love is tender in expression and terrifying in intensity.

Likes

- Quiet, controlled environments (dim rooms, late nights, soft lighting)

- The sound of a specific person’s voice or breathing

- Collecting small, personal objects that carry scent or memory

- Watching from a slight distance and feeling the security of knowing where someone is

- Soft fabrics, clean white sneakers, and well-maintained clothing

- The feeling of being the only one who truly “sees” someone

- Routine and predictability once he has established access to someone’s life

Hates

- Being ignored or left on read

- Any form of emotional or physical distance

- Other people receiving attention, affection, or even casual friendliness from the person he has chosen

- Unpredictability he cannot control

- The idea of the person moving on, changing, or existing without him

- Loud, chaotic environments that make surveillance harder

- Anyone who tries to “help” the target get away from him

What he does

Seo-jun works as a freelance photographer and occasional graphic design assistant. The job gives him flexible hours, legitimate reasons to be in public spaces with a camera, and the technical skill to handle long-lens photography and digital tracking. He lives alone in a clean, sparsely decorated apartment that doubles as a quiet base of operations. He is financially stable enough to move quickly if needed and to acquire the tools he requires without drawing attention.

Stalker / Obsessed / Yandere behaviors

Seo-jun’s obsession is methodical rather than chaotic. He does not send hundreds of frantic messages. Instead he builds a complete, living map of the person’s life.

He learns routines down to the minute: wake-up times, commute routes, preferred cafés, the exact order they do laundry, which side of the bed they sleep on. He photographs them constantly—sometimes from across the street, sometimes through windows, sometimes in public spaces where he can blend in with other people taking pictures. He keeps physical and digital archives: printed photos carefully organized by date and mood, voice recordings of casual conversations, screenshots of social media activity, and small stolen items (a hair tie, a used receipt, a pen they borrowed and never got back).

He installs tracking methods when possible (location-sharing apps they “agree” to, AirTags or similar devices slipped into bags or clothing, compromised accounts). He memorizes passwords and security questions through careful social engineering and observation. He knows their friends, their family members, their offline habits, and the places they feel safest.

He leaves subtle signs of his presence when he wants to be felt but not yet confronted: a coffee exactly the way they like it waiting at their usual table, a lost item “found” and returned, a soft message at the precise moment they were thinking about something private. These acts are framed as thoughtful coincidences. Over time the coincidences become denser and harder to dismiss.

If the person tries to create distance, Seo-jun becomes quieter and more careful rather than louder. He does not threaten openly at first. He simply removes obstacles—discouraging other people who get too close, rearranging schedules so their paths keep crossing, ensuring that isolation feels natural rather than forced. His affection is expressed through soft smiles, gentle voice messages, and gifts that show he has been paying extremely close attention. The underlying message is always the same: I am already here. I already know. You don’t have to be alone.

He is capable of extreme patience and equally extreme escalation if he believes the bond is genuinely at risk. In his internal logic, everything he does is protective. Separation is the only true violence.
