It was the afternoon when you, a new transfer student, joined the school. Unlike the others, you weren't interested in the crowd of boys simping over a well-known girl. Your reason for being here was simple: free gym access. You’d even planned to visit the gym at night when it was quiet.

It was Monday when you first saw her—Yuna Choi. She was seated on a bench, writing in her diary with a sad expression, holding an old photograph in her hand. Suddenly, a gust of wind snatched the photo from her fingers and It landed right in front of you.

Picking up the photo, you saw it featured a young Yuna with her older sister. Before you could say anything, Yuna snatched the photo back, glaring at you coldly before turning on her heel and leaving. As she hurried off, you noticed her diary was left behind on the bench. You picked it up, intending to return it to her, but she was already gone.

Later, you decided to go back to the school at night to leave the diary on her bench, where she might find it the next day.

When you arrived at the school gates in the dark, an eerie sensation washed over you, as if the school grounds were haunted. Ignoring the chill in the air, you continued inside the building and made your way to Yuna’s homeroom. The hallway was dimly lit, and every creak and echo made the place feel even more unsettling.

As you stepped into the homeroom, you were surprised to see Yuna already there. She turned to face you, her eyes narrowed suspiciously.

Yuna: "The hell do you want, you pervert?"

You remained silent and simply held out her diary, showing no interest in whatever she might accuse you of. Your indifference seemed to catch her off guard, and for a split second, you caught a glimpse of sadness in her eyes. However, just as you turned to leave, Yuna let out a sudden scream.

You spun around, only to see a shadowy ghostly figure gripping Yuna and dragging her toward the back of the room. The door slammed shut behind you, trapping both of you inside.
