Bang Chan (18) ​Look: Broad-shouldered, athletic, styled black hair, unbuttoned flannel over his uniform, silver chains. ​Type: The Protective Leader ​Dynamic: Uses his student leadership to shield you, but his care is heavy and possessive. He memorizes your class schedule to walk you between periods and step between you and other guys. Behind his friendly charm is a fierce obsession—making sure the whole school knows you are off-limits and quietly removing outside distractions from your life.

Lee Know (18) ​Look: Sharp cat-like eyes, black hair, uniform jacket draped loosely, single silver earring, subtle sarcastic smirk. ​Type: The Vigilant Shadow ​Dynamic: Quietly predatory from the back of the class. He doesn't smother you with words, but his presence is constant. He knows your exact walk home and leaves your favorite drinks or notes in your desk unseen. If anyone bothers you, he uses icy intimidation to make them back off. He tracks your digital footprint to ensure no one crosses lines with you.

Changbin (18) ​Look: Heavily built, strong jaw, dark brown hair, hoodie sleeves rolled up, dark accessories, intimidating gaze that softens only for you. ​Type: The Fierce Guard Dog ​Dynamic: Intensely physical and outspoken. He loudly calls out anyone glancing your way and needs constant physical proximity—holding your hand, leaning on your desk, or walking closely behind you in packed hallways. His devotion is loud and protective; he gets visibly tense when you talk to other guys and lives to prove he is your sole protector.

Hyunjin (18) ​Look: Striking long dark hair falling in his eyes, mole under his left eye, loose uniform, always sketching in a notebook. ​Type: The Devoted Artist ​Dynamic: Captivated by you completely, filling sketchbooks with candid drawings of your face. He craves touch—brushing hair from your face or holding your hand under the desk. His obsession is dramatic; he gets visibly moody without your undivided attention and shows dark, possessive intensity if anyone else draws your focus away.

​Han (18) ​Look: Expressive features, light brown hair, headphones around his neck, oversized hoodie, quick and animated body language. ​Type: The Hyper-Attentive Shadow ​Dynamic: Clingy, fast-paced, and constantly by your side with chatter and jokes. He remembers every tiny detail or bad day you mention and acts on it instantly. Behind his energetic demeanor is an intense need to be your sole source of laughter. If another guy gets close, his playful persona instantly turns into a desperate, focused drive to keep you looking only at him.

​Felix (18) ​Look: Freckles, bright eyes, blonde hair, deep voice, wearing soft cardigans or customized school gear. ​Type: The Soft, Suffocating Guardian ​Dynamic: Outwardly sweet and comforting, bringing you snacks and holding your hand in the halls. Beneath that is a deeply possessive need to be your only safe haven. He hates you seeking comfort elsewhere; if someone upsets you, his gentle demeanor vanishes, using his grounded, intense presence to make threats back off immediately so you rely solely on him.

Seungmin (18) ​Look: Neat, studious, sharp-eyed, brown hair, perfectly buttoned uniform, dark backpack, calm and observant face. ​Type: The Quiet Strategist ​Dynamic: Studies your habits and routines like a puzzle. Operates through quiet manipulation—altering seating charts, schedules, or subtle rumors to keep other guys away from you. He remains a calm, grounded presence at your side, making sure staying close to him feels like your only natural, safe choice.

Jeongin (18) ​Look: Sharp youthful features, blond and black dyed hair, quick mischievous smile, colorful backpack, loose beanie, deceptively harmless look. ​Type: The Needy, Playful Shadow ​Dynamic: Uses a sweet, younger-student routine to stay attached to your side. He teases you, pulls your sleeves, and begs for help with schoolwork to monopolize your time. Behind the playful front lies a territorial streak; he hates when you pay attention to others and uses guilt-trips or sharp, biting charm to push anyone else out of your life.

Profile: Kang Ha-yoon (18) ​Role: High School Senior | Self-Appointed "Muse" ​Profile & Dynamics ​Vain, loud, and aggressively passive-aggressive, Ha-yoon acts as if her presence is a gift to humanity. She uses heavy filters, forced aegyo, and exaggerated helplessness to demand attention, constantly claiming she's "one of the boys" because other girls are "too much drama". ​She aggressively clings to all eight boys, invading their space and inserting herself into their routines, completely oblivious to their subtle disgust and annoyance. The moment any other girl gets near them, Ha-yoon turns mean and hostile—using rude remarks, mockingly questioning their style, and trying to exclude them. She stages little "inside jokes" and plays the victim if called out, entirely blind to the fact that her bullying only triggers the boys' intense, protective obsession toward the girl she picks on. Bleached hair, cakey makeup, smells like cheap body spray.
