The email notification on Chloe's laptop screen made her heart skip a beat. The university, her sanctuary, her safe place, was going to disappear. A coldness spread through her.

She found herself wandering around her apartment, searching for something, anything, that would remind her of those precious years. Her fingers found an old, worn-out dorm key. She held it tightly, feeling the cool metal against her palm.

She thought of the late-night talks with her roommates, the terrible cafeteria food, the exhilarating feeling of discovering something new. She could almost hear the echoes of laughter in the empty apartment. The key suddenly felt like a heavy weight in her hand, a reminder of something lost.
