Everyone is freaking out about how ‘sudden’ Haru’s change of heart is and I think they’re failing to realize something pretty important. Haru swimming professionally is something that’s been discussed since the beginning of the season, so its obviously something he was thinking about.
He probably didn’t have this HUGE sour taste in his mouth for competitive swimming, it was likely just one or two things stressing him out that he couldn’t get out of his head. And I know everyone is like “wtf shiny pool, thats what changed his mind?”
NO. IT WAS NOT THE POOL. IT WAS HARU BEING GIVEN A CALM OPTION TO SWIM NEXT TO PROFESSIONAL SWIMMERS. He made the conscious choice to do so, thereby eliminating his stress.
Then, seeing the really nice Australian swimmer, Haru was able to see someone who is genuinely happy in his career path and obviously loves to swim.
HARU’S REALISATION FADES FROM THE SWIMMER DIVING, NOT FROM LOOKING AT THE POOL.
PLEASE DO NOT REDUCE IT TO THAT.
SEEING OTHERS SWIM IS A VERY PROFOUND EXPERIENCE FOR HIM AND THAT IS PERFECTLY ACCEPTABLE WRITING.
Sometimes seeing something like that (if you have an emotional attachment to the action) really does make you just snap into a certain mindset. Furthermore, I don’t think Haru is so much ABSOLUTELY sure that he will be happy as much as a competitive swimmer as much as he now knows that it is POSSIBLE and he was able to see that the world like Rin does.
To me thats actually pretty profound…
Plus, if you hadn’t caught on to the turmoil of insecurities freaking him out in the previous episodes - of swimming becoming nothing but an expectation, an obligation he has to do to make a living, instead of what it’s always been for him: his expression of self, his link to his friends…. then you have not been paying attention throughout ES.
All Rin does is puts it into another perspective, a perspective where he’s not tied down but just held steadily by someone who’s a friend (potentially all his friends, but that’s just my thoughts) - opening his eyes to the fact that there would be somone there for him, no matter what, that would pull him back up in case he felt like sinking and drowning. The pool and the pro swimmers, they’re just the trigger objects that enable him to see it for himself, as opposed to hearing it from someone else.
