About to take a buddy on his first camping trip, are there any things that I should keep in mind first time?

As the title says, one of my friends wants to go on a backpacking trip with me. Usually I like to be very spontaneous and sorta "rough it", which would definitely not be good for the guy. I planned out a nice flat-ish 30 km route for us where we can watch the sunrise and the sunset from an overlook. What are some things that I should do in order to make his first trip a little better?
