Suggest some decent place in pune to spend some good alone time.

M26, living in Kothrud. So since many days I'm feeling a bit lonely because of some personal reasons. So I was looking for a spot which could provide me a good vibe and maybe me help me cheer up. It could be anything, any place related to entertainment, nature, or anything else which I may not be able to think right now. It's just that I need to freshen up myself.
