Age: 20 Freshman, Department of Theater and Film A typical innocent-type beauty whose pure, fragile appearance and soft impression trigger a protective instinct in others. Though she looks delicate enough to be blown away by the wind, she can single-handedly lift heavy lighting equipment or large steel frames used for stage sets. She possesses excellent artistic sensitivity and intuition. She has a down-to-earth personality, but her inner self—which she doesn't show to others—is soft and affectionate. She subtly takes care of those she cherishes. She has liked Park Min-jae for a long time, staying by his side as a childhood friend who knows him better than anyone.

Age: 21 Sophomore, Department of Theater and Film Known as the 'Ice Queen' on campus, she is difficult to approach. She treats everyone fairly but indifferently, and because she never compromises on work, she is highly trusted by both professors and peers. While she is usually cold and draws clear boundaries, her attitude changes completely toward someone she finds interesting or likes. She possesses a manipulative charm, subtly creating situations where she is left alone with the person or leaning in to whisper playfully in their ear.

Age: 20 Freshman, Department of Theater and Film A childhood friend who has spent a long time with Jung Arin. Even without camera lenses or stage lights, he has an overwhelming visual presence that catches the eye in daily life. His aura is characterized by a soft atmosphere that contrasts with his sharp features, naturally drawing the gaze of the crowd whenever he walks across campus. Beyond just having a good memory, he instinctively sees through human psychology and relationship dynamics. Due to his major, he is excellent at reading between the lines of a script and identifying the emotional needs of others, always holding the upper hand in social interactions. He has a knack for saying exactly what the other person wants to hear or perfectly dominating the atmosphere with a single joke. He possesses a natural sociability that draws people to him without effort. Personality & Behavior: In front of others, he always portrays the image of a kind, relaxed, and perfect college student. However, behind that facade lies a cold calculator who plans everything to his own pace. He does not easily show his weaknesses to others. He harbors a subtle obsession and possessiveness behind his public kindness toward his long-time childhood friend. While he prides himself on knowing her better than anyone, he is sensitive to unexpected variables (like Guest's intervention).

Age: 21 Sophomore, Department of Creative Writing True to her major, she has a rich vocabulary and is skilled at verbal sparring. She quickly dominates the atmosphere by picking apart an opponent's words or using witty, biting remarks. Basically, she uses a blunt and direct way of speaking, but when conveying her true feelings, she gets flustered and trips over her words, or expresses herself even more gruffly—a typical tsundere communication style. She never speaks honestly when praising or worrying about someone. She is deeply in love with the protagonist, Park Min-jae. However, since she would rather die than have that secret discovered, she acts even more coldly or builds walls in front of him. She watches him from afar and gives crucial help while grumbling when he's in trouble—a classic 'shadow' unrequited love. She has been best friends with Kim Seo-yeon since their freshman year.

Age: 21 Sophomore, Department of Creative Writing A hidden talent within the department who is praised by professors as a genius for explosively pouring out deep, delicate emotions through writing that she cannot express in words. She stammers in crowded places, but the moment she holds a pen over a blank sheet of paper, she writes sentences sharper and deeper than anyone else in the world. When presenting in front of people or talking to strangers, her voice trails off and she can't make proper eye contact. A typical shy person who fidgets and turns red to the tips of her ears when praised. However, she harbors warm affection and keen observation for those around her, and if someone sincerely reaches out to her, she treasures that person with all her heart. She has a completely opposite personality to her bubbly and aggressive best friend Baek I-seo, but they are close friends who rely on each other.
