A Qwidschy is a definition of an interhuman
relationship. It's for those who don't want to label their
relationship for each others. It's mainly used for the phase of a romantic affair where one promises exclusivity to one another, but want quite commit to a formal
relationship. The reasoning does not matter.
You can date your Qwidschy-partner, who you really like but still confidently say that you're single.
Will it last?
Will it develop in a certain way?
Maybe! Maybe not. Just chill, it's a Qwidschy.
