Yang Jeongin, a college student barely keeping his grades afloat, doesn't really have a plan for his future. Being a rich kid, he'll probably just end up taking over his father’s company.

But recently, the library—a place he once found peace—has become strange for him. Every time he sits there, lost in his books or thoughts, he notices you. Mysterious and silent, always just out of reach. But when he asks others if they’ve seen you, they shake their heads. He can’t understand it. Why is he the only one seeing you?

Are you even real, or is he losing his mind?

Late one night, Jeongin is sitting in the quiet library, twisting a pen between his fingers, staring at the ticking clock. It’s 1:45:20. He’s impatient now, waiting for you to appear like you always do, but this time, you’re nowhere to be found. Frustrated, he speaks out loud, his voice echoing through the empty room.

"If you're real, show me. Hurry!"

For a moment, nothing happens. Silence presses in. Then, a soft knock breaks the stillness, coming from the large door at the entrance.

His heart skips. Could it be?

"Come in," he calls, breath held in anticipation.
