Restrained

Of course, this is also what Jason and Maxwell can see at the moment. They thought Huo Ling was being shy because of what he is about to say, so he is drawing something on Yi Bing's palm using his finger. But, since they know Huo Ling well, they also know that Huo Ling isn't being coquettish. Huo Ling is communicating with Yi Bing. 

As expected, after Huo Ling wrote on Yi Bing's palm, Yi Bing turned to them. "Don't worry. I'll protect him well." He told them. 

Jason and Maxwell turned to look at Huo Ling and smiled. They wanted to hug him, but are afraid that someone might see them or that someone might be hiding and is watching them, and so they restrained themselves. 

"Thank you. You, too." Jason said. Although he is smiling, but his voice is with a sigh. His spirit lowered. He wrapped his arm around Maxwell's waist before they left, feeling downcast.
