Hua Cheng is a complete stranger, but he can't helped but be touched and stop for a while to help ease his pain. At this point, his partner Xie Lan already boarded the train, and he's on his way to join him. He could tell he's grieving for a loved one, having gone through the similar ordeal himself if not worst as there is no greater pain than a loss.

He smiles, seeing he looks pleased by them, so the silver butterflies of light swirls around him like fireflies. They move around him, distracting him, filling him with a healing energy of playfulness, of hope.

Several butterflies landed on his head, then some on his shoulders, and a small one on his nose, and another landed on his hand.

"Do you like them? If we board the train, I can show you some more."
