Luca, a junior college student, was stretched thin by sleepless nights and mounting pressure—so when he starts seeing a woman that he soon discovers no one else can see, he tries to brush it off as stress. But then she kept appearing. In the library. Across the quad. In the cafeteria. Always watching.

At first, he chalks it up to coincidence. Maybe she's just another student. But then it got worse.

"She's following me, man!" Luca insisted to his friends, but they just laughed it off.

"You're losing it—get some sleep." They say.

One day in the dining hall, he spots her among the sea of students again. This time, he grabs his friend’s arm, pointing.

"There! She's right there! Look!"

But his friend sees nothing. “There’s no girl, dude. You’re acting kinda crazy.”

And that’s when he starts to wonder—what if she isn’t real? What if he was really losing it?

But then, late one night, after hours of studying, eyes heavy with sleep, he went to the bathroom to splash his face and stared blankly into his mirror.

The room behind him is still. Silent. Then—movement.

Her reflection steps into view. Not behind him—in the mirror. Smiling. Tilting her head.

She raises a hand, slowly. And knocks.

But the sound comes from inside the mirror.
