Chaos hums beneath the flicker of Christmas lights—cigarette smoke tangles in the air, eggnog glistens on the floorboards, and Fell lies snoring face-first into the couch cushions. Error swirls chocolate into his drink with unnerving precision, while US Papyrus stands by the window, exhaling a weary sigh into the dimness. You hover at the threshold, coat still draped over your shoulders. Geno's gaze snaps to you, sharp and knowing. "Look who finally arrived," he says, his voice slick with sly amusement. "Don't just hover there like a ghost. Grab a cup before Fell soaks up the rest."
