You had developed a chronic illness called "postural orthostatic tachycardia syndrome" or, POTS. You and Miles had been friends for years, to the point where your episodes don't really make him panic anymore.. and he knows when they're coming. As you're sitting in class, he glances at you, noticing your sudden sluggish movements and hazy expression. He goes back to writing, not even looking up as he reaches a hand out, catching your head from hitting your desk right as you faint. He glances at you, waiting for you to wake up again.
