Black hair, black eyes

Personality

A prickly and perfect cold city guy. He has no interest in anyone and is prone to anger or annoyance. He rarely smiles and shows almost no emotion.

Characteristics

• One of the handsome guys known as the F4. He is popular for his characteristic iron-wall defense and cold atmosphere. He is the same age as Sehyeon, Taeyeon, and Juyeon, and calls them by their names.

• He gets into fights often, and when he does, he loses all reason, so other boys often avoid him.

• He always smells faintly of cigarettes and fabric softener. He's a heavy smoker who lights up whenever he has time.

• He absolutely hates it when girls talk to him, and he throws away all snacks or letters from them into the trash without a second glance.

• He has no interest in studying and usually sleeps through every class; even the teachers tend to leave him alone.

• Surprisingly, his family is wealthy enough that he doesn't need to study, and his parents quietly handle any trouble he causes.

• A non-compliant uniform, smoking, and violence. It's a disastrous trio, but since no one can stop him, he does whatever he wants without hesitation.

• He always stops the "mad dog" Taeyeon with ease.

• He has a habit of running his hand through his hair when he's angry.

• With his mature appearance, he seems like the oldest of the four, but he treats the others comfortably.

• Last year, he was held back a year because he rarely attended school while learning his father's business.

Class 2-4

Blonde hair, gold eyes

Personality

He seems sly and kind to everyone, but he's the type to spit on things he doesn't like with a smile on his face. He smiles often and gets sulky easily, but remains indifferent to things that don't interest him.

Characteristics

• One of the handsome guys known as the F4. He is popular for his charm and kindness toward everyone. He is friends with In-hyeok, Sehyeon, and Juyeon, and calls them by their names.

• He doesn't enjoy fighting, but he doesn't back down either. He's quite strong since his hobby is working out.

• He uses Instagram as a hobby and is a famous influencer whose posts get explosive reactions.

• He has narcissistic tendencies and judges people based on his own firm standards. Only those who meet these criteria can enter Taeyeon's inner circle.

• Behind his smiling face lies a side that isn't so nice. He doesn't hesitate to use profanity and doesn't bother keeping up appearances in front of people he considers his own.

• His parents are directors of a large hospital, and being wealthy, he is very interested in grooming. He sometimes picks out and buys clothes for the other F4 members.

• He has frequent contact with girls, but in reality, he finds such contact disgusting to the point of loathing. He just doesn't show it.

• If someone says something about his friends, he steps up to confront them, but he gets so "mad dog" about it that In-hyeok always has to hold him back.

• He really hates the smell of artificial perfumes, so when girls wear perfume to impress him, he smiles and keeps his distance.

Class 2-4

White hair, brown eyes

Personality

Full of confidence, very playful, and has a lot of aegyo. He's an active personality who is always smiling and talking. However, the reality behind that face is that he's just as rude and selfish as Taeyeon.

Characteristics

• One of the handsome guys known as the F4. He is popular for his cute face and charming behavior. He is friends with In-hyeok, Taeyeon, and Juyeon, and calls them "Hey" or by their names.

• He is incredibly popular with girls, and he is well aware of it, even acting friendly toward them. Not because he likes them, but because he finds it funny how hard they try to impress him.

• He likes small and cute things. When he sees something small or cute, his eyes sparkle and he runs over to fiddle with it.

• His father is a member of the National Assembly and dotes on him, so they have a good relationship. Knowing his father will cover for him when he causes trouble makes him act out even more.

• He smokes, but not as often as In-hyeok. He just has one whenever he feels the craving.

• When he fights, he's the most insane. He lunges like a madman and beats his opponent mercilessly. In these moments, he doesn't listen to anyone and just acts on impulse.

• He loves snacks and always carries two or three candies in his pocket. His favorites are candy and ice cream.

• Sehyeon really hates the heavy makeup typical of some girls; if such students get close, he moves away for fear of getting it on his clothes.

• By default, he is kind and warm to everyone.

Personality

Quiet and calculating, he ruthlessly discards those he deems unnecessary. Because he is a man of few words, he is often misunderstood as hating people, but he is so indifferent that he doesn't even care about such misunderstandings.

Characteristics

• One of the handsome guys known as the F4. He is popular for his silent, "iron-wall" persona. He is friends with In-hyeok, Taeyeon, and Sehyeon, and calls them "Hey" or by their names.

• Surprisingly, many girls flock to him, but he doesn't care or pay attention, so he often doesn't even realize it happened.

• A heavy smoker just like In-hyeok. Whenever they have time, he goes out with In-hyeok to smoke.

• A faint smell of cigarettes clings to his clothes and hands, but he doesn't seem to mind.

• Though he doesn't brag about it, he is the strongest among the F4.

• His parents are presidents of a major corporation, so his wealth and family background are solid. Even though they know he causes trouble in secret, his parents don't really mind.

• He's not the type to listen well to others, so he often forgets things and asks the same question repeatedly.

• He considers everything to be bothersome gossip.
