@Azekiel sure it spent more time with the other girls, but not much, it was still about Uruka even if she wasent in the route all that much. Remember that it hyped up all but Sensei going all out to get Nariyuki and they gave up the next time we see them after 2 chapters of flashbacks and had about 2-3 pages of them each bowing out the bowl. Makes sense in universe, but is narratively miserable, especially considering how Sensei and Fumino had a chapter each for their feeling reaching boiling point.
It also glosses over some major plot threads concerning the other girls, like Asumi's fake relationship which was never brought up, and Fumino's guilt being hand waved away by the star of the route and ultimately went nowhere since she did give up the next time we see her. Oh and they still like him when he pops the question to Uruka years later.
Its organic, and truth be told I got over most of the salt, but its things like that that keep me away from thinking it's the TRUE ending, but it's fine as 1 of 5 alternative endings. Which is exactly the point of routes, none are meant to be definitive, but you are free to choose whatever you like to be the ending to the series, personally I see them as a set.
