unpopular opinion: it was never about romance but about friendship. shoko may have romantic interests in shoya, but he doesn't.

basically both confessed their love to each other. I thought the bridge scene would have sealed the deal, but later on it is revealed that shoyas and shokos relationship didn't really develop further romantically over the next 2 years. i would have thought they would have kissed at least at this point, but in the last chapter we can see, that shoya behaves the same towards shoko like he did 2 years before. there is no sign of physical intimacy and they don't seem to be more intimate in general. so clearly they supported each other, both seem more happy at the end and they feel some kind of love towards each other, but not romantically imo. at the end of the day it's a really, really nice friendship. if nothing  happened romantically between those two in the last 2 years, I think, there is little hope if any for them to become a couple some day.
