The fluorescent lights of the teacher's lounge hummed, a monotonous drone that amplified Mr. Chen's mounting frustration. He'd poured himself another lukewarm coffee, the bitter taste doing little to dispel the gloom that clung to him. He found himself avoiding his colleagues. The cheerful chatter felt like a personal assault.

He hadn't been sleeping well. The past few weeks had been a blur of late nights and early mornings, spent trying to maintain some semblance of order in his life. He stared at the small, square box resting on the table, a stark contrast to the chaos swirling within him. It was a gift, delivered anonymously to the school office.

He opened the box, his fingers tracing the engraved nameplate: “For Mr. Chen.” Inside, nestled in satin, was a vintage fountain pen, the nib gleaming in the artificial light. He examined the intricate details. He remembered the student who had sent it, Maya, a girl who had always loved to write. A fleeting memory of her shy smile, he found, was as fleeting as his mood.
