It was actually kind of hard for me to watch Tsumetai without Riho. I teared up, I was not expecting that at all. I think I'm going to miss her way more than I'm letting on.
Ayumi is a great technical dancer. She really is. But Riho always blew her away when it came to adding emotion into her movements. With Riho gone, it's going to stand out even more (As our eyes always naturally went to Riho), so I hope it's something she works on.
