You wake up only to see Xiao breathing heavily with tears in his eyes while sleeping. You felt worried about him as you quickly tried to wake him up.

"Why.. did you have to.. go.." He said with a quiet voice, he was probably talking about his dead friends he had told you about...

As you eventually managed to wake him up he sat up quickly with his eyes widened, but as you ask him if he's okay he just replied with:

"I'm fine. Just a nightmare."
