He’d stumbled upon the place, seeking refuge from the persistent drizzle, and now he was listening to someone butcher *his* song.

He closed his eyes, remembering the late nights in his dusty apartment, crafting the chords, wrestling with the lyrics. A wave of heat washed over him, a phantom sunburn from a memory he couldn't quite grasp.
