Mori crying over Kiara got a lot of attention, but also worth pointing out is that Mori was slowly coming out of JWU for the duration of the stream after starting off really sleepy. She was getting more awake and excited as the show was going on and had plenty of things to talk about, but then she suddenly ERUPTS into full-on cheering when it's Kiara's turn. She really does love her.
