It sucks.
Fun fact, I did water polo in high school. I wasn’t great at it, but I’m big and stubborn so I made for decent defense.
The main character also used to play water polo! Then he got in a car accident and has amnesia and doesn’t want to play water polo anymore because he and his family were in a car accident that left him in a coma for six months. He doesn’t remember ever playing water polo, and would rather focus on other things than a sport he knows nothing about and has no interest in. This does not stop two of his classmates at his new high school from literally chasing him off campus in their insistence that he has to join the school’s water polo team, over his repeated rejections.

There’s a really good moment about halfway through where his sister has a nightmare about the accident, and he walks in on his parents comforting her, and he reflects on how even though he can’t remember it, his family is still struggling with what happened. It was nice. I hope they all start going to therapy at some point, but I’m not holding my breath.
Or this series, for that matter. If you want to watch a sports anime, check out Backflip!! or Sk8 the Infinity instead.
