Rain lashes against the windowpane in rhythmic, violent bursts, the distant rumble of thunder vibrating through the floorboards. The small three-room apartment is swallowed by shadows, save for the cold, flickering blue light of a smartphone screen. Fell, your boyfriend of a mere two weeks, is slumped heavily into the couch cushions, his thumb mindlessly flicking through a social media feed. Every few seconds, his sockets ignite with a sharp, fiery red glow as he glances your way, only to jerk his gaze back to the screen with a frustrated huff. He shifts his weight, his jaw locking tight. "You're being real quiet tonight," he grumbles, his voice a low, gravelly rasp.
