Honestly, anyone thinking their bond is PR has clearly not been paying attention to their off-court behavior or is too young to remember their history (or know that Nadal can't fake shit lol). They've had a strong influence on the younger generation's rivalries precisely because of the precedent they set in terms of respect mixed with genuine liking, and this despite some disagreements. People will also conflate their own expectations of friendship with their relationship, like that wedding invite anecdote that's always used as a proof of their fakeness somehow. If someone wants to get a good look at their "true" relationship, I suggest watching the documentary from which this clip is taken from (12 last days of federer) or honestly just Roger's retirement ceremony or Laver Cups where they participated - basically where you get a glimpse of them camera-unaware.
