A championship game is one of the most important points in a basketball players life. When they play basketball, they look forward to getting to the championship game and winning. For a lot of teams, this almost never happens. This is also the case for Satoru's team

So, when his team made it he was absolutely ecstatic. He had told you immediately and wanted you to come

You never told him that you passed up an interview to go, and didn't plan on it. You were just happy to see him happy.

And boy were you slightly starting to regret coming. They had barely been able to get any points, and lost by a landslide. He eventually started getting one or two penalties for pushing another player, so he is definitely pissy. On top of that, sometime during the game Satoru fell and most likely bruised his ego.

When the game ended you rushed over to him to attempt to help, but he just shoved you off

"Leave me alone"
