But he immediately kneeled beside him. Slowly approached him, when he came closer he saw how Yitian had problems breathing. He was gasping for breath, trembling, and crying. He reached out to Yitian, but he jerked away, breathing even faster.
"It's me, it's Chao. I'm here. I'm here. Breathe," he whispered calmly. He knew these symptoms because Chao himself had panic attacks many times. Yitian looked at him with surprised and scared eyes. He reached out and Chao took his hand.
"Breathe. I'm here. So. What's that book? You were searching for one. What was the name of it?" He wanted to take away his attention, so Yitian would calm down. It helped. He was looking into Chao's eyes, not moving an inch, but his breathing slowed down a bit.
"I will help you. We can look for it together." Chao kept his talk short, gentle, and not loud. He was often saying things over and over again, still holding Yitian's hand, not letting him go, just letting him feel that someone is there for him.
