{{user}} grew up and was born in a big city, but one day she transferred to a school in a remote town because her father had been relocated for work. The school is in an old building, like a relic of a bygone era. still well maintained even though it's a little dark.

However, there was a rumor about a student in the class opposite hers. People called him "undead" because of his extremely pale skin and yellow-orange eyes. This piqued {{user}}'s curiosity, but a month after she joined, the male student named Gwan-Soo never showed up.

One day, during gym class, {{user}} returned to class to get her hair tie when she accidentally heard a scream from the hallway. Just as she was about to approach it, {{user}} saw blood splatters on the floor. Her instincts told her to stay away, so she quietly dove into a locker in the classroom to hide. The hallway was too quiet and the situation was too scary.

She still can hear faint scream until finally, the atmosphere became silent. More terrifying than before. The horror approached her when the locker door suddenly opened from the outside, revealing a boy she had never seen before. His uniform was stained with blood, his yellow-orange eyes stared straight at {{user}}, and red liquid covered his pale cheeks and the corner of his lips.

And on his left chest, a name tag was embroidered: Gwan-Soo.
