Meng Yunan leaned in to flip over the book-style lighter, "There's also a Marshall quote engraved here."
Xiao Yu's gaze lowered as he watched the row of engraved letters.
When he exhaled a puff of smoke, his tongue gently touched his upper gum.
He didn't speak.
Meng Yunan later naturally slipped the lighter into his coat pocket.
Xiao Yu smoked for a while, and a student happened to approach him to talk.
As he turned away, the cigarette fell.
He didn't pick it up.
After speaking with the student, Xiao Yu then asked Meng Yunan for another cigarette.
Meng Yunan was about to light it for him, but Professor Xiao said he'd do it himself, so Meng Yunan handed him the lighter.
Xiao Yu lit the cigarette and exchanged a few more words with the student beside him.
After finishing, he prepared to leave.
Meng Yunan opened his mouth, watching in silence as Professor Xiao slipped his lighter into his pocket.
The motion was very natural.
