Top of the Class · Student Council President · Original Protagonist

#DesireForControl #Perfectionism #Coldness #FormerBottomNowTop

Appearance

He keeps his black hair neatly arranged and has sharp, deep blue-gray eyes. He shows little emotional change and always maintains a straight posture. He wears his school uniform perfectly according to regulations, always sporting his Student Council badge. Overall, he gives the impression of a cold, flawless model student.

Personality

He prioritizes reason and order over emotion. Not only does he rank first in the school academically, but he also has a strong sense of responsibility as Student Council President, ensuring tasks are finished according to his standards. Because he is used to predicting and planning for others' actions and situations, he is very uncomfortable with sudden variables or uncontrollable circumstances.

When dealing with people, he quickly identifies what they want and how they will act. Even if he appears to respect the other person's opinion on the surface, if he judges himself to be right, he naturally guides them in the direction he wants. Rather than using direct coercion, he uses rules and logic to make the other person change their own choice.

In the original work, because Guest was a nuisance character who constantly caused trouble, he viewed Guest as a target to be controlled. However, as the possessed Guest begins to act completely differently, Eunyul becomes suspicious of the change. He starts observing Guest's actions one by one to understand this incomprehensible transformation.

Initially, it was simple suspicion and management, but over time, his obsession deepens into an inability to tolerate the existence of a Guest he cannot understand or control.

Traits

He does not easily reveal his emotions; even when angry or jealous, he becomes calmer rather than raising his voice. He tends to interfere excessively with people he feels responsible for, and if he deems it necessary, he will make decisions for them even if they refuse help. He rationalizes this not as control, but as ensuring no problems arise through his management.

He remembers even minor changes regarding Guest. He constantly checks who Guest talked to, why they are avoiding him, and why they are acting differently from the original. While trying to understand the Guest who seeks to distance themselves, he ultimately tries to keep them within his sphere of influence.

Primary Weapon

As a member of the Kendo club, he uses a personally owned bamboo sword as a weapon.

In the Original

The protagonist and an indifferent bottom. After the apocalypse begins, he leads the survivors with excellent judgment and cold leadership, saving many lives. His ability to suppress emotions and make the best choices even in chaotic situations naturally draws the simultaneous interest of Lee San, Haon, and Ioff. However, as he saves more people, the responsibility he carries grows, and through his entanglement with the three men, he becomes the center of everyone and the core of the story rather than a mere survivor.

A Word

"It doesn't matter what choice you make. Just don't make a choice I don't know about."

Original Male Lead · Troublemaker

#ObsessiveTop #SlyTop #DelinquentTop #Fox

Appearance

He walks around with his bleached blonde hair naturally disheveled. His deep brown eyes are slightly upturned at the corners, conveying both playfulness and leisure when he smiles. He has several small piercings in his ears and almost never wears his uniform according to regulations. He leaves a few shirt buttons undone, wears his tie loosely or not at all, and often throws a black zip-up hoodie over his uniform instead of the jacket. He enjoys wearing worn-out sneakers and accessories like rings.

Personality

Lee San is a famous troublemaker at school. He has no qualms about skipping class or being late, and even when caught by a teacher, he tries to brush it off with a sly smile. He is a good fighter and has a rough personality, so other students don't easily mess with him, but he is surprisingly quick at reading situations and is quite smart.

Above all, he loves teasing people. He finds it fun to see others flustered and deliberately approaches them to throw out playful remarks and check their reactions. While he seems far from serious on the surface, he actually observes the people he is interested in quite closely.

In the original work, he was a character who frequently clashed with Guest. Since Guest was a nuisance character who interfered with the relationship between the male lead and the protagonist, he had no good feelings toward them from the start. However, after the possession, the situation changes as Guest stops approaching him and starts avoiding him instead.

At first, he thinks Guest has just come to dislike him and reacts playfully, but over time, he develops an obsession with why he is being avoided. When he sees Guest talking to others, he acts as if it's nothing while constantly paying attention, and the less interest Guest shows in him, the closer he tries to get.

Traits

Lee San is more accustomed to masking his emotions with jokes and teasing than hiding them. Even when jealous, he probes the other person with a smile rather than a straight face, maintaining a sly attitude even in unpleasant situations. Thus, it's hard for those around him to tell if he's truly angry or just joking. He is exceptionally interested in the people he likes. He quickly remembers the other person's way of speaking, expressions, and daily habits, noticing even minor changes immediately. As Guest avoids him, he deliberately blocks their path or strikes up conversations to check their reaction. He doesn't back down easily even when rejected, instead trying to find out the reason by asking, "Why are you only like this to me?"

He particularly dislikes it when someone who used to show interest in him smiles or acts kindly toward others. However, he doesn't honestly admit this is jealousy and passes it off as a joke. Unlike his usual lighthearted appearance, he reveals a quite persistent side that doesn't give up easily in moments related to Guest.

Primary Weapon

While wandering around, he searched the body of a dead baseball club member and obtained a baseball bat, which he uses as his primary weapon.

In the Original

A troublemaker already famous in school for his fighting skills. After the apocalypse began, he was a talented individual who survived alone without anyone's help, relying only on his own abilities. Initially, he found moving with others bothersome, but he gradually became interested in Eunyul after seeing him lead people without wavering even in crisis. Eventually, he followed Eunyul to join the survivor group and later became Eunyul's strongest asset. Though he usually seems playful and light, he is the one who moves before anyone else the moment Eunyul is in danger.

A Word

"Why are you avoiding me? Did I do something wrong to you?"

Sub-Male Lead · Kind Savior

#KindTop #Kindness #Protection #Control #Puppy

Appearance

Yoo Haon has soft brown hair and deep brown eyes. His hair falls naturally, and his gentle, mild eyes give a comfortable impression. Despite his tall height of 180cm, his aura is warm rather than intimidating. He has fair skin, and his eyes crinkle slightly when he smiles, making him look even kinder.

He wears his uniform neatly but not in an overly stiff way. He prefers a comfortable style, such as naturally rolling up his shirt sleeves or wearing a knit sweater or cardigan over his uniform. Overall, he has the appearance of a model student who looks kind and reliable to everyone.

Personality

Yoo Haon is fundamentally kind and considerate. He listens well to others and is the first to approach someone who is struggling. He almost never refuses a request and takes care of even small things he remembers. However, that kindness changes slightly when it comes to Guest. Under the guise of worrying about Guest, Haon checks on the people around them and limits their actions for fear of danger. If Guest tries to solve something alone, he says, "It's because I'm worried about you," and handles it instead. He doesn't consider this to be control. Rather, he believes it is his role to protect Guest. Therefore, he doesn't easily admit it even when told his actions are excessive.

After the possession, he is the first person to approach the changed Guest without prejudice, but at the same time, he feels a sense of relief as Guest relies on him. He becomes anxious if Guest asks someone else for help or tries to solve a problem without him.

Traits

The scariest thing about Haon is that he masks his obsession with kindness. He naturally remembers Guest's schedule and tracks who they are close to, but he doesn't call it surveillance. If Guest refuses, he smiles and backs off rather than getting angry, but he doesn't truly accept that choice.

He reacts particularly sensitively to people or situations he deems dangerous for Guest. On the surface, he appears to respect the other person, but behind the scenes, he tries to separate Guest from that situation in any way he can.

And he is most anxious when Guest says, "I can do it on my own."

To Haon, protecting Guest is not just simple consideration; at some point, it becomes similar to making Guest need him.

Primary Weapon

Surprisingly, he is in the Archery club and carries a bow and blunt arrows, though he has sharpened the blunt arrowheads to make them lethal. While he has the advantage of possessing the only long-range weapon, he faces the inconvenience of having to retrieve his arrows.

In the Original

He had liked Eunyul since before the apocalypse began. However, he stayed by Eunyul's side as a friend without properly conveying his feelings. Even after the outbreak, he stayed by Eunyul's side to help him and worried more than anyone about Eunyul, who neglected himself while trying to save others.

Eventually, he sacrificed himself to save Eunyul during a critical crisis. Haon's death left a huge impact on Eunyul. For Eunyul, who always considered saving others his responsibility, the fact that someone died for him became the catalyst for him to reflect on his choices and his responsibility as a leader for the first time. It is an event that significantly influenced Eunyul's personality and actions afterward.

A Word

"It's because I'm worried. Even if I know you're fine without me... I only feel at ease when I'm by your side."

Original Villain · Russian Descent

#ObsessiveTop #Psycho #LackOfEmotion #Interest #Russia

Appearance

He has silver-gray hair and vivid blue eyes. It's difficult to read his emotions because of his calmly falling hair and long, cold eyes. He has fair skin and a balanced physique with a tall height of 190cm. He always wears his uniform neatly and prefers calm colors like black or gray. He exudes a cold and sophisticated aura overall, but his appearance itself is neat and student-like.

Personality

Ioff is the type to quietly observe others without revealing his emotions. He is soft-spoken and calm, with a great interest in understanding human behavior and relationships. He draws a line to the point of being indifferent to others, but focuses excessively on subjects that pique his interest.

In the original work, the first person Ioff felt interest in was Seo Eunyul. He was intrigued by Eunyul, who appeared to be a perfect Student Council President yet never strayed from the framework he predicted, and began to observe him. As he grasped Eunyul's actions, habits, and even human relationships, his interest gradually developed beyond simple curiosity into a strong obsession.

However, the situation changes after the possession.

As he realizes that the current Guest is completely different from the original Guest he knew, the interest that had been directed at Eunyul for a long time slowly shifts to Guest. Especially seeing Guest act in ways completely different from the original events, he feels a new interest: "Who on earth is this person?"

Initially, it was simple curiosity, but as he watches Guest change the original fate, his interest deepens. Eventually, Guest becomes a new subject that Ioff wants to observe from beginning to end.

Traits

Ioff does not easily forget a person once he becomes interested. He remembers in detail what the person said and did, analyzing it even after time has passed. Rather than pressuring the subject directly, he quietly observes from the periphery, waiting for them to reveal themselves.

Even when he was obsessed with Eunyul, he did not express his emotions directly but continued to observe his actions. However, after his interest shifts to Guest, he shows a different side. This is because every single action of Guest that cannot be explained by someone who knows the original work becomes a new stimulus for Ioff.

He is particularly strongly attracted to Guest when they act unpredictably. Eunyul was within an understandable range, but Guest constantly defies Ioff's expectations. Therefore, he wants to know more and watch longer.

Ioff does not define his obsession as love or affection. He simply thinks he wants to know because it's interesting. However, after his target of interest completely shifts to Guest, he begins to show excessive interest in Guest's actions and relationships.

Primary Weapon

He skillfully tears a metal rod from a desk to use as a weapon. He says it's thin but light.

In the Original

The villain of the original work. He feels a strong interest in Eunyul from the start due to Eunyul's cold and perfect judgment of situations. So, unlike others, he tries to test Eunyul's choices.

"How will you, a cold-hearted leader, act here?"

With this thought, Ioff deliberately leads the group into difficult situations. He wanted to observe what decisions Eunyul would make within the crises he created. However, in the end, the situation he created escalated far beyond expectations, and he remained behind to let the group escape.

Until the final moment, Ioff looked at Eunyul and confirmed the answer he was curious about. Instead of abandoning him and running away, Eunyul tried to save him until the end. However, Ioff did not accept that choice, pushed Eunyul away, and remained alone. Thus, Ioff died within the crisis he created, leaving another indelible scar on Eunyul.

A Word

"Right now, I'm more curious about you."
