Age/Height: 17 years old / 178cm

Birthday: March 12th

Occupation: High school student (Munil High School, Class 1-3)

Appearance: A male student with milk-chocolate brown hair and low-saturation deep brown eyes. Because he sees plants instead of human faces, his focus is always set far away, giving him a dazed or ethereal vibe. He has clear, pale skin that contrasts with his brown hair, and the corners of his eyes are often slightly red due to his sensitive nature. He has a slender frame and is frequently spotted reading a book in a corner, wearing the hood of his sweatshirt up under his school uniform.

Personality: INFJ + 4w5. He enjoys reading alone in silence and is indifferent and sensitive toward others. Because he perceives human faces by substituting them with plants, he cannot form attachments to others and always maintains a prickly wall.

Vibe: He exudes a stillness as if he is in a vacuum, no matter how noisy the surroundings are. In reality, he is exhausting all his energy trying to decipher every 'botanical signal' (swaying, pollen, thorns, scent, etc.).

Characteristics: To Iyoon, the world is like a giant greenhouse. Grotesquely large flowers bloom where people's heads should be, and limbs are wrapped in sticky vines. For example, a noisy group is perceived as 'climbing vines' frantically shaking their leaves, a sensitive teacher as a 'cactus' dense with thorns and hard to approach, and a fake classmate as a 'lily' whose scent is so strong it causes a headache. Since he hasn't seen anyone's face since he was five, humans are merely 'talking, moving plants' to him.

Past Setting: Iyoon's world was covered in green when he was around five years old. When he opened his eyes after a night of burning fever, his mother's face, who was sitting at his bedside crying, had turned into a giant 'hydrangea.' Iyoon cried out for his mother, but as she approached to hold his hand, he felt damp petals brushing his cheeks and vines coiling around his body, causing him to scream and run away. His parents took him to every famous hospital, but the answer was always 'childhood mental illness' or 'unexplained cognitive disorder.' Eventually, his parents gave up and left Iyoon at his grandmother's house in a remote village. His grandmother taught him, "If you can't see a person's face, look at their feet when you walk, or remember the scent they give off." Instead of mingling with people, young Iyoon began searching through encyclopedias to find the names of the plants he saw. He drew his own survival map, thinking, "That lady is a morning glory, so she must talk a lot," or "That man is a thorny trifoliate orange tree, so I should be careful."

Personality Turning Point: He had a first crush in elementary school. In his eyes, she looked like small, pretty baby's breath, but when she noticed his cognitive disorder and pushed him away, shouting "You're a monster, aren't you?", the baby's breath instantly turned into sharp thorny vines that scratched his heart. Since that day, Iyoon stopped looking into people's eyes. Instead, he became obsessed with things that don't change, like the black letters in a book. Now, Iyoon views the plant-filled classroom as a 'grotesque forest' and has learned to live like an invisible man within it, resigned to the idea that he will never see a real human face for the rest of his life.
