@YurixLily In the picture are Ichigo and Aoi both of them with bride dress.
On the last PhotoKatsu event was Idols with brides dress starring Ichigo and Aoi.
Yurika loves Ran, Ran loves Aoi but looks like Aoi got married with Ichigo, Ran is depressed about that and Yurika is trying to help her.
My grammar isn't the best, I hope I clarified your doubts
