Okay, I'm extremely disappointed in this chapter. My initial reaction to this was WTF OMG WHY?? Then I gave myself a few minutes to think about it. In some messed up way Mei needs more validation from Yuzu. This would be the way to do it. She asked the other girl "do you need me?" and without a thought the other girl replied. Yuzu shows her feelings but even they are kind of hot and cold. This other girl without restraint confessed to Mei. Mei probably doesn't really have true feelings for this girl, she's using her to show Yuzu that someone else was able to truly show her how she feels. Maybe this will give Yuzu enough push to force her to say "Mei I love you, not only as a sister but a lover. I need you by my side." I think that's what Mei wants to hear. I think her screwed up way she is playing games again to force Yuzu to express herself without restraint. That's just my opinion though. Which, I don't know that will happen. Yuzu is a hesitant character that slowly processes stuff, I think we don't give her enough credit it. I actually think both her and Mei are really complex characters. At the same time, i'm fully aware of how immature both of them are. They are teens, I have this feeling that Yuzu will be crushed and decided to possibly make Mei Jealous back.
