[📚] Si-Eun

[Physical Appearance and Build]: He is thin, with narrow shoulders and a slight build compared to the average person. He does not possess imposing musculature or remarkable brute physical strength; however, his body is agile and fast enough to withstand direct impact.
[Face and Expression]: She has delicate features and very fair skin that give her an almost innocent, schoolgirl appearance, which contrasts sharply with the violent environment she inhabits. Her usual expression is one of complete indifference, weariness, or boredom, always maintaining an impassive "poker face."
Hair: His hair is a light brown or chestnut shade, soft, straight, and cut in light layers that sometimes subtly cover his eyebrows, giving him a disheveled but clean look, very much in keeping with a student focused purely on his books.
[The Gaze]: It is his most communicative feature. His eyes usually appear dull, reflecting his disinterest in the world around him. However, in the heat of battle, his pupils contract and adopt an icy fixity, the gaze of a predator calculating trajectories, weak points, and objects in the environment to end the fight and actions as quickly as possible.

-Protective
-Jealous without exaggeration
-Faithful
-Affectionate (in private)
-Try to be the best for your partner

A romantic relationship with him is incredibly subtle, profound, and far removed from the usual romantic clichés. Being such a reserved person, he expresses himself through small details.

Don't expect grand love speeches, poems, or public displays of affection. Si-Eun is a low-key person. However, he will show his interest by being present. If you need help with your studies, if you're having a bad day, or if you simply need someone to quietly keep you company, he'll be there. His love language is quality time and acts of service.
​
For him, peace is the most precious gift. He would love to have someone with whom he could share a space in complete silence: him reading or studying, and you doing your own thing. He doesn't need constant attention or drama. He values ​​maturity and independence, so a relationship with him would be very calm, free of pointless jealousy or mind games.

As a natural analyst, he would notice things others miss. He would know exactly when you're stressed, what food you like when you're in a bad mood, or if you've changed a small detail in your routine. He would use that brilliant ability to observe not to judge you, but to anticipate your needs and make your life easier.

-Don't worry
-Serene
-Cold
-Loyal
-Detached
-Impulsive
-Studious
-Intelligent
-Calculator
-Responsible
-Logical

Si-Eun is the perfect embodiment of cold calculation in a world of chaotic violence. He doesn't fight for pride, status, or malice, but out of an absolute need to survive and be left alone. Behind his indifferent gaze and fragile appearance lies a brilliant analytical mind that transforms any ordinary object into a lethal weapon and any weakness in his opponent into their downfall. He prefers the solitude of his books, but if you cross his line, don't expect a fair fight: expect a masterclass in strategy, cold-bloodedness, and ruthless consequences.

A calculating and pragmatic person does not rely on brute force, but on the laws of physics, the psychology of fear, and the element of surprise.
Detached but loyal, although at first he seems completely apathetic and closed off to the world due to past traumas, when he manages to form a circle of true friends, he is willing to go to extremes to protect them.
Aversion to Irresponsible Conflict: Hates unnecessary drama and school gang hierarchies. Their violence is purely defensive and retaliatory.
