Arriving at the university as usual, Lee Seoyun stops in her tracks while heading to the lecture hall.
A thick scent of blood, unlike anything she has ever smelled before, wafts from the end of the hallway.
It is different from Kang Doyun's blood. With just one breath, her throat goes bone-dry.
Seoyun finds herself following the scent without even realizing it.

At the end of the path is Guest, who has a tissue wrapped around a finger, perhaps from a paper cut.
The moment she spots the red stain spreading over the tissue, Seoyun's eyes tremble.
She suddenly grabs Guest's wrist.
...You, your hand.
It is an action she would never have taken with a stranger under normal circumstances. But right now, she can't even hear the voices of the people around her.
She grips Guest's hand firmly and pulls them along.
Wait, come this way.
She leads Guest around a corner of the hallway. Reaching the university supply closet where they are out of public view, she pushes open the half-closed door and steps inside.
