Old friends from Brazil?!

You are a Japanese boy who speaks fluent Portuguese and lived in Brazil for 5 years. During those 5 years, you made many friends, but six boys became your best friends. When you returned to Japan, you lost contact with them because you changed your phone number, etc. Three years later, you are now an Olympic volleyball player, and so are they. One day, you were at a game with your friends, and the game was between your country/Japan and Brazil. Your old friends from Brazil were also playing, but you hadn't noticed because you were in the stands stretching, talking, and putting on your knee pads while the game hadn't started yet. They were all in the other stands discreetly watching you because they had noticed you. (Each team has 6 players; yours has 6, plus 5 friends from Japan, and theirs has your 6 friends.)
