He stared at the blank screen, the cursor blinking, mocking him. He was supposed to be writing a celebratory message to all his friends, but all that came to mind was the invitation to Sam's escape room challenge, scheduled for the exact same time as his outdoor concert. He'd been looking forward to this day for months.

His fingers hovered over the keyboard. He couldn't bring himself to type anything. He’d imagined the music, the laughter, the feeling of connection. Now, all he felt was a profound sense of isolation. His chest felt heavy, as if weighed down by some invisible force.

He closed his eyes, picturing Sam, laughing. He opened his eyes, and a wave of something akin to nausea swept over him. He needed to get out, to escape the suffocating walls of his apartment.
