Aww, that's lovely! With the anime coming out at some point, hopefully there will be a lot more interest in the series so others wander in as well.

I'm no expert on her but I find Eva is almost a 'big sister' sort of person... to anyone who isn't Neil. And then she is in a very teasing sense to him too. She struck me as someone who was thoughtful and serious but still playful enough to make jokes (and bad puns too).

I hope you have a great time playing her! :)
