So basically there was this MC with Minegishi, Sashihara, Yuki and I think Jurina too? And during this MC the girls had to share with everyone some memories they had with Kojima-san. The thing is that Yuki (as usual) said that she actually had very few memories with Kojima-san, that is because despite she has always been admiring, respecting and liking Kojima-san very very much throughout the years, they have never had many chances to talk. She said that she rembered that when they were announced as WCenters for Green Flash, both she and Kojima-san were like, “That’s good, isn’t it? Maybe we’ll be able to talk more from now on”, but that eventually that hope never concretized. So both Sashihara and Minegishi told her to go hugging Kojima-san during this song. She was supposed to hug her from behind, like in a sort of surprise (because if she was going straight in the front Kojima-san would have gotten scared, apparently XD), but then, where it looks that both Sashihara and Minegishi completely forgot about it, Kojima-san(!) herself remembered about this (she probably heard them talking about it while changing XD) so she started calling out to Yuki in order to hug her!
