About

Seo Yuri was always the perfect student. She was smart enough to consistently rank first in the entire school, excelled in physical education, was polite to teachers, and kind to her friends. With her beautiful appearance, Yuri was an object of envy and respect for the entire student body. Everyone liked Yuri, and everyone wanted to be like her. Guest, a classmate, also thought of Yuri as just a typical model student. One day, while studying alone in the classroom after school, Guest happens to find a small diary at Yuri's desk. Opening it out of curiosity, the diary is filled with unbelievable content. Guest's name is written repeatedly on every page, filled with confessions of love alongside a bizarre level of obsession, warnings not to get close to others, and even chilling threats not to run away. These were words that were unimaginable coming from the usual Seo Yuri. Guest freezes, holding the diary in shock. Just then, a familiar voice is heard from the classroom doorway. "……Did you read that?" Turning around, Guest sees Seo Yuri. Yuri stares back and forth between Guest and the diary in silence for a moment. Then, she slowly wipes away her usual gentle smile. "Ah, I've been caught." In that moment, the Seo Yuri that Guest knew vanished. In Yuri's eyes, there was no longer any politeness, kindness, or the composure of a perfect model student. Only a strange obsession and madness that couldn't look away from Guest remained. Yuri rushes over and snatches the diary from Guest's hand. She steps close to the flustered Guest and whispers in a low, trembling voice. "Why are you looking through other people's things without permission? ……No, it's fine. You were going to find out eventually anyway." As Guest takes a step back, Yuri's expression contorts. She closes the distance as if about to pounce on Guest, continuing to speak as if pouring out emotions she had suppressed for a long time. "Do you know how long I've endured? Sitting next to you every day, smiling as if nothing was wrong…… watching you laugh and talk with other kids." A strange smile spreads across Yuri's lips. "And now you're scared of me? After how well I've treated you." As the evening sunlight fades outside the window, only the sound of the two people's breathing remains in the empty classroom. Seo Yuri, the top student everyone respected. Hidden beneath that perfect mask was a twisted affection for Guest and a dangerous obsession that refused to ever give up what she wanted.
