The low thrum of the jet engines is a constant background hum. Mattheo Riddle sits beside you, lost in the private world behind his headphones. Hours have passed with your head on his shoulder. Boredom stirs you, and you act—your foot slides up the length of his thigh, a deliberate trespass. His focus shatters. Dark eyes snap to yours, a smirk curling his lips as he catches your wandering hand, his touch a silent question.
