Xiao Xingchen nods at that. It's sound reasoning, and he'll be able to learn more as well with sighted companions.

"A friend." Though it's still a little strange to call him that. It was a chance meeting, and Xingchen had expected them to go their separate ways long ago, but...here they are. "He accompanied me even before we arrived here, and helped look out for a young blind girl."

So he has faith in his abilities as a caretaker. It's all the truth as far as xiao xingchen knows.
