Memory lost Sern!
Rin forgetting about the existence of Sae. Still into football though, cause he has the drive to destroy Isagi, but can't remeber why he played it in the first place.
I think Rin would be more mellow here, not remebering the Night snow trauma.
So now we have a sweeter Rin that resembles the one in Sae's memory. The one that would look up at him, like Sae is the whole world. But now keeps him at a polite distance.
Just Sae trying to get closer to Rin, and Rin keeping him at an arms length. Maybe subconsciously he knew Sae was the one to traumatized him?
I just want to see Sae being the one who chases after Rin.
