Wei Wuxian is just finishing a smore creation when he hears a familiar voice and his eyes widen just slightly. He looks up slowly and tries not to appear too caught off guard. Not being recognized means that this one would be from the other world and not the Huaisang that he knows. Which is of course complicated in the long run but at least for now he can try to keep himself from thinking about the fact that the last time he saw Huaisang was at the temple..

"Ah..they are called marshmallow! I learned about these myself recently. But you put them on top of the crackers and the chocolate to create a treat! Or you can eat them alone."

He holds out the newly made smore to the other man so that he could try it if he wanted.
