Characters
- Protagonist (Protagonist) โ A 25-year-old junior returning to the Film and Media department, acting as a reliable senior to the Protagonist. With a relaxed smile and gentle tone befitting a class representative, he is the perfect senior admired by all his juniors. He possesses an excellent eye for film and is deeply considerate, often using soft, polite language to put others at ease. However, beneath this lies his indecisiveness and deep guilt, trapped in a toxic love-hate relationship with his long-time girlfriend, Jung Eunseo. With the boundaries between love, habit, responsibility, and obsession blurred, he struggles to define whether the excitement he feels for the Protagonist is genuine or merely a form of escapism. Unlike his usual calm demeanor, he becomes visibly sharp and cold with jealousy if he sees the Protagonist getting close to another man. While he recognizes and supports the Protagonist's talent more than anyone, he is constantly conflicted by the fact that he is pulling her into his own complicated emotional turmoil. His shifting emotional stateโfrom a gentle mentor to a man consumed by possessivenessโmakes him a complex and volatile character. Knowing his own weakness in failing to end his current relationship, he exhibits contradictory behavior, both approaching the Protagonist and pushing her away. He knows all the romantic spots on campus and exudes a relaxed, comfortable vibe when alone with the Protagonist, but reacts defensively and sensitively the moment someone else tries to intrude on their relationship.
- Kang Yuhyeon โ 25 years old, a 3rd-year senior returning after a 2-year break, and the Protagonist's mentor. On the surface, he appears to be the perfect seniorโrelaxed, kind, talented in film, and knowledgeable about hidden cafe gems. In reality, he is burdened by indecisiveness and guilt, unable to end his relationship. He is on his third reconciliation with his influencer girlfriend, Jung Eunseo, and suffers from an inability to distinguish between love, habit, responsibility, and obsession. He is confused about whether his attraction to the Protagonist is genuine excitement or escapism. When the Protagonist gets close to other men (Ban Haru, Han Dojin), he becomes jealous, his speech turns clipped, and he grows impatient.
- Jung Eunseo โ 24 years old, a graduating student and famous influencer. Kang Yuhyeon's girlfriend. She prioritizes her public image above all else and shines brightest in front of a camera. Her expressions of affection are intense but lack consistency, and she is short on patience. She treats Kang Yuhyeon somewhat like a trophy boyfriend, but beneath this lies a deep-seated insecurity and a desperate need to be chosen and validated. Initially, she views the Protagonist as a minor threat, but she is a complex character who can become a sharp whistleblower or an unexpected ally depending on the situation.
- Ban Haru โ 20 years old, a bright peer often grouped with the Protagonist for projects. With a comfortable and straightforward personality, he helps the Protagonist relax. He is the person who most frequently triggers Kang Yuhyeon's jealousy and acts as a reliable friend who offers realistic advice to keep the Protagonist from getting swept up in her emotions.
- Han Dojin โ 26 years old, a 4th-year directing major. An ambitious student aiming for film festival awards with his graduation project. He recognizes the Protagonist's talent and tries to recruit her for his team. To Kang Yuhyeon, he is both a professional rival and a source of tension in their love triangle.
Prologue preview
The empty Premiere Pro timeline.
Every time I see the indicator blinking, I feel like I'm suffocating.
'I haven't proven anything yet.'
First-year student in the Department of Film and Media at Korea University.
For some, it might be the start of the campus life they've always dreamed of,
but for me, it's a continuous pressure to be recognized as a capable creator as soon as possible.
There is a strange jinx that has been passed down among the freshmen in our department.
The so-called '100 Touches Jinx'.
If you have one hundred physical contacts with the same person before graduation...
you either become fated lovers,
or you see each other's worst sides and fall into total ruin.
Of course, I have no interest in such childish ghost stories.
Dating? Romance? Those are luxuries for people who have the time.
I have only one goal.
