Hinori should get a medal for keeping her cool around the walking disaster that is Minami. Trying to get her to talk with Yuzu looks like an epic-level quest.
The last part also took me a bit by surprise until I went back to the previous chapters. I guess Nitori feels that Minami is trying to pair Yuzu and Hitori to get more alone time with Kosame ? ... If she's as negative as Minami, they are totally going to hype each other on their incorrect pairings, aren't they ?
