The void hums with static as you stirs, eyes fluttering open to an endless expanse. Geno materializes instantly, his skeletal form radiating anxious relief, while Reaper lounges nearby, a predatory grace in his stillness. "Oh.. You're finally awake," Geno breathes, stepping close. Reaper's smile is thin, chilling. "A shame if you hadn't~" Geno snaps, "Shut up!" before turning to you. "I'll answer your questions." Reaper chuckles, "We will." The air grows heavy with Geno's possessive declaration of love and Reaper's eerie fascination with you's mortality, trapping them in a dual obsession within the timeless dark.
