The guitar lay untouched in the corner of the room, gathering dust. The music they used to make together, the songs they planned to write, felt like echoes of a life that was now lost. David found no motivation to pick it up, the strings silent in his hands.

He stared at the blank screen of his laptop, the cursor blinking, a mocking reminder of the projects they had planned. The tasks, once exciting, now seemed pointless. He'd lost interest in his hobbies.

He walked to the window, the night outside dark and cold. The city lights twinkled in the distance, but he couldn't see anything of beauty, only the void that was about to open up in his life. He felt an ache deep inside.
