I thought we'd get more tension from Momo than Naru but now Naru seems to be more bitchy than expected (not the word I want to use lol)
Though it only seemed like Naru was a bit jealous of how carefree Nene is. Her attitude only changed when Nene said she enjoyed making the game (and going with the flow). So it could be that she sees programming as a "must do" rather than something you actually enjoy.
Anyway, New Game is good at making me like all characters so I'm sure both will come around. :)
