This is just the OVA episode from "We never learn" Basically here, the characters are invited by mc's mom's friend, as she opens up a new business and that is providing marriage facilities, well basically she opened up a place where people can get married. So all of them try on the outfits including the mc and they all have a photo shoot, It's a really good episode and even if you ship one girl with the mc, it's still fun to watch as all of them get embarassed and their cute reactions were something. I liked it, it was fun for me to watch Do I recommend? Yeah,sure
