The two walked a long distance, accompanying Wu Lingyu to dispose of her sanitary napkin at the garbage truck and then to the library.
When Xu Qingfan returned to the doorway of Class 16, half of the third period had already passed.
"Excuse me, teacher, I had something to attend to." Xu Qingfan knocked on the door, waited for the subject teacher's nod, and then went back in through the rear door to his seat.
"Brother Fan, I didn't know what you wanted to drink, so I bought you a bottle of Coke," Wu Shichong whispered, pointing at the Coke and the school card on the desk.
Xu Qingfan picked up the half-bottle of flat Coke and looked sideways at Xiao Ruawen.
"Pay attention in class!" Xiao Ruawen pushed his head forward firmly, squinting as if she was looking at the blackboard.
Xu Qingfan slipped his hand under the desk and pinched her, then uncapped the Coke and took an unabashed swig directly from the bottle.
