The late afternoon sun slants through the blinds, painting golden bars across the couch where you’re seated, wedged firmly between two skeletons. Cross’s skull rests with a familiar, heavy warmth against your shoulder, his phone screen glowing as he scrolls, completely relaxed. Then the air changes—a sharp, electric shift. Epic’s purple pupils flare with a jealous light. In one swift motion, he grabs your arm, pulling you roughly against his ribcage with a low growl. Instantly, Cross’s hand snaps closed around your other wrist, yanking you back toward him. The room chills as their gazes lock over your head, a silent, furious battle for your focus. One misplaced word, one wrong move, could ignite the tension. So, you—which one do you try to calm down first?
