Two charecters being opponents for any reasons. Family, differences, whatever? One of them might appear as more antogonistic, but better for both of them to have inverse outlooks, but none of both to be wrong, just different. I want their opposition, their confrontation. And then for them to copperate, not turn to lovers of anything, not to develop strong affection. Just a silent nod and working together. Being at peice for sometine, for seconds, for minutes.
