Synopsis
''When Chaerin Eun becomes the protagonist of the romance novel she is reading, she expects a fairytale ending with the novel’s love interest, Jeha. But when a bizarre twist makes her realize the story is not playing out as it does in the book, she’ll need the help of an unlikely character from her class to defy the new storyline and find her happy ending -- if only she can figure out who this ‘Unknown Extra’ is first!''

Chaerin Eun
The main character. She has taken the place of the female lead in her favorite romance novel, Chaerin Eun. On the day Jeha Yu, the male lead, is supposed to confess to her, there is a zombie outbreak. Chaerin is bitten on her hand and returns to the morning of the same day. She quickly realizes she is trapped in a Groundhog Day scenario where she is stuck in the emerging zombie apocalypse and restarts the day every time she dies.

When she is transported into the novel, all characters other than Jeha appear to her as black, featureless silhouettes. Since she had the worst reputation in the class, she struggles to convince the other characters about the zombie apocalypse. As her classmates come to trust her, she becomes able to see them clearly.

After Chaerin survives the first entire day of zombies and goes to sleep at night, she has a dream where she is seeing through the eyes of the Unknown Extra.
