[Hak has experienced the rush of adrenaline many times. A dream like state of being where every single one of his senses peaked and awareness heightened. Typically it was during moments when his life or Yona's was in danger. But he's experiencing that at this moment.
Every twitch of muscles in her hands. The way her breath catches within her lungs. The pressure as her weight pushes against him. There's a split second of fear that he'd overstepped his boundaries, but that fear eases as she reciprocates.
