from what was in earlier chapters and this chapter Nanase has a crush on Beyond, the way she acted when first meeting Haruka and the way she kept watching him, Haruka senses it also, Haruka isn't sure about their relationship, but she was trying to help Nanase by pushing Beyond to try to get along with her. Beyond's speculations that Nanase is into martial arts is probably right, the way her movements are described, it would also go along with her dance and idol training. I wonder if Nanase and Beyond met before and she's been following him since then, but Beyond doesn't remember the incident??
