I'm glad Nanami got out of her head and into reality when she got back to the apartment. Imagine seeing this from Koyuki's perspective. Hell, I doubt she knew that Nanami heard about the confession, and then the next time she sees her, she's kind of an asshole? Perspective is so important, and Nanami is a bit ignorant on it. It's crazy how innocent she seems after having multiple relationships and people attempt to get with her in the series so far. I'm still blown away on how she didn't realize Aoi was trying to get with her a couple of chapters ago.
