Hi. I will say in few months that I'm new also in Zurich, even that I already spend 2 months in there. This time (hopefull before the end of this year) I will buy a ticket for one way. It's nice to have a forum where you can read the experience of another romanian and you can learn how to handle some situation in Swiss.
You should check out the Social Events thread to see what's happening, and how you can join in to meet some lovely people! If you're after lovely local people, get into some regular sporting team / activity ...
