回複：I have similiar experience 8 years ago, finally found my boss

and his boss didn't like each other. I did nothing wrong, just involved into a political game. i struggled with them unnecessary, and many people got hurt, I don't time to write my story now to share with you, but do learn a lot from it.

I think you did nothing wrong either, don't take it too seriously. Maybe it's better when talking with your boss and his boss about your matter, don't mention others, like A.
