It's refreshing that Neneko doesn't act like the typical anime female who gets super-pissy at the male lead for being perverted and boots them to lower earth orbit, neither does she get all lovey-dovey jealous in the process.
Neneko even says that it could be a misunderstanding the first time Ren calls Takeya master. OMG, A CALM, RATIONAL ANIME FEMALE WHO ACTUALLY CONSIDERS THAT IT COULD HAVE ALL BEEN A MISUNDERSTANDING, IT'S A MIRACLE!!!!!
