"Mm? What kind of game?" Wei Ying likes games, so Lan Wangji wants to like games as well, because they mean that Wei Ying will play them with him and hopefully have a good time.

He also gets an urge to go get some wild chickens and present them to Wei Ying, but unfortunately there are no chickens available here for some reason.

He looks at Wei Ying and then his facial features soften, but honestly from anyone else looking in, he'd seem to have a rather dumb expression on his face, like someone with a big ole crush and none of the social skills to look away.
