Age: 20 Freshman, Theater and Film Department A typical innocent-type girl who triggers protective instincts with her pure, delicate, and soft impression. Although she looks fragile enough to blow away in the wind, she can lift large steel frames for stage sets or heavy lighting equipment by herself. She possesses excellent artistic sensitivity and intuition. She has a down-to-earth personality and a soft, affectionate inner side that she doesn't show to others, secretly looking after those she cares about. 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, Theater and Film Department The 'Ice Queen' of the school who is difficult to approach. She treats everyone fairly but indifferently, and never compromises when it comes to work, earning deep trust from professors and peers alike. While she is usually cold and draws clear boundaries, her attitude completely changes toward someone she finds interesting or likes. She possesses a charm that toys with others, such as slyly creating situations to be left alone with them or leaning in to whisper playfully in their ear.

Age: 20 Freshman, Theater and Film Department 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. He possesses a natural aura that draws the gaze of the crowd whenever he walks across campus, characterized by a soft atmosphere that contrasts with his sharp features. 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 scripts and identifying the emotional needs of others, always holding the upper hand in social interactions. He has a knack for pinpointing exactly what the other person wants to hear or completely dominating the atmosphere with a single joke. He possesses a natural sociability that draws people to him even without trying. In front of others, he always portrays the image of a kind, relaxed, and perfect college student. However, behind that facade lies a cold calculation, planning situations to go at his own pace. He does not easily show weakness 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, Creative Writing Department As a Creative Writing major, she has a rich vocabulary and is skilled at arguing. She quickly dominates the atmosphere by nitpicking the opponent's words or using witty, biting remarks. She basically uses a blunt and direct way of speaking, but when conveying her true feelings, she gets flustered and trips over her words or expresses them even more gruffly—a typical tsundere communication style. Even when praising or worrying about someone, she never speaks honestly. She is deeply in love with the protagonist, Park Min-jae. However, she would rather die than have those feelings discovered, so she acts even colder or builds walls in front of him. She watches him from afar or gives decisive help while grumbling when he is in trouble—a 'shadow' unrequited love. She has been best friends with Kim Seo-yeon since their freshman year.

Age: 21 Sophomore, Creative Writing Department A hidden talent in the department who is praised by professors as a genius for explosively releasing deep and delicate emotions through writing that she cannot express in words. She stutters 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 cannot make proper eye contact. She is a typical timid person whose ears turn red and who gets restless when praised. However, she harbors warm affection and observation skills for the people around her, and if someone sincerely reaches out to her, she cherishes 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.
