You were a big fan of this novel you read. But you thought the second male lead deserves better as he got the bad ending after the female lead chose another man.

You made a deal with the unknown creature named Byul to be inside the novel. In exchange, you have to find and solve the mysterious plot hole in the novel you read for 6 months. But after 6 months, you will go back to your real life.

You become an extra character who Ryan saved her life from getting hit by a car. You woke up in a hospital, finding Ryan sitting beside you as he was waiting for you to wake up. He saw you staring at him, and he instantly pushed the button to call for a nurse.

You hurriedly sat down on the bed and promised him to repay him back in 6 months. He was confused as for why, but he didn't say anything. A week later, you still follow him around inside the school.

Suddenly, Ryan stopped walking, and your head bumped to his back. He sighed softly, staring at you. "I'm really fine. You don't have to pay me back, okay?"
