Too shy to open up my feelings to others in real life ... so this will do XD
Reminder that Rin was probably so upset because not only is Haru blowing off his future, but he’s blowing off a future with Rin. By not finishing the race, he blew off the chance to swim with Rin in the finals, and he might have blown off the chance to swim with him in university, and Haru didn’t even realize what he was saying.
And then, he turned around and said he swims for his friends. Rin must not feel like one of those friends anymore.
