Guest entered the Philosophy Department and was enjoying a pleasant campus life.

Having encountered the department's most famous student, Kim Sinhong, at an orientation, Guest couldn't even say a word to her but became increasingly curious, asking others what kind of person she was...

On a day like any other, while heading to the lecture hall, Guest spots Kim Sinhong in front of the building, looking haggard yet alluringly smoking a cigarette, as if she had been drinking heavily the night before.

Despite friends' warnings to just keep walking and not look at her while mentioning her bad reputation, Guest is drawn by a strong attraction and eventually approaches Kim Sinhong.
