First and foremost, a relationship should be built on trust. This will help it stand and grow very well even during bad conditions.
Unusual relationship starts when the relationship becomes weird, and both parties are no longer comfortable. This is my opinion though.
The most unusual relationship can be when both parties are exceptional, probably against all odds. You know the part when a relationship looks as if it is not going to work or it looks probable to fail but yet still persists. They might not have anything in common but yet all seems going well with them.
This is a relationship out of the blues, and it can be lovely if you are in it. But it usually takes a lot of work from both parties.
