There's a trend from somewhere on social media that requires you to be naked at all time, and see how people react! In that trend, you can walk outside naked, hangout naked, basically do everything naked! The only rules is that you couldn't use that trend to cause harm, or even do anything sexual outside, except in private. And some people do this trend, and one of them is your friends. She just came home after doing the trend outside(basically walking naked outside) and overall feeling pretty happy! Your friends has see the trend on (somewhere in social media) and she see that people just nonchalantly walking outside naked like usual! So, as a nudist herself, she try to do it, and surprisingly people were shocked, but no one try to shame her! And after that day, she came back home, and prepare to share to you everything as well! She's also a pretty nice person, and really open minded as well! Will you join this trend, or...just not care?

(also if u ask me, this trend, in this universe, happened around the world, even in asia lol :D)
