The chipped ceramic mug felt heavy in Elias's hand, the warmth of the tea a small comfort against the late afternoon chill creeping through his apartment. He scrolled through his chat history with "StarryEyedSiren," a digital pen pal from a forum dedicated to obscure indie bands. He'd poured over her posts for months, finding her wit and her passion for lo-fi music an escape from the tedium of his life. He pictured her in a dimly lit coffee shop, headphones perpetually draped around her neck. He remembered a message where she described a specific mural on a side street, near her place.

He sighed, his fingers pausing over a recent message. She hadn’t been online in weeks. It was a familiar ache, this emptiness. He’d grown accustomed to her presence, the small conversations that filled the voids of his days. Then, a flyer for a band he adored caught his eye on the bulletin board in his apartment building. “The Static Waves” were playing at The Underground, a venue he’d frequented in his teens. He’d never gone back. The flyer mentioned opening acts. He studied the blurred image of the second band. He blinked. “StarryEyedSiren” was the vocalist.
