Pulls a Kishi, or a Kubo?!!!!!!
My shipper heart is going doki doki
What if ishida pulls a kishi on us???...

He won't, he's actually a good writer XD
Rukia and Ichigo didn't need it spelled out, it's implied. There were many things after the SS arc that implied it. Starting off with, but not limited to, the fact that Rukia was consistently the only one that "made his rain go away". There was nothing that Orihime could do about that, it was always Rukia.We can disregard the eye gazing, but from a reader's standpoint, the totality of the evidence still seems to suggest that the author wants Ichihime to happen. Unlike in Naruto, we aren't told Ichigo is in love with anyone. We aren't told Rukia is in love with anyone.
Really, Ii there a single moment in all 686 chapters where we're told Rukia is in love with Ichgio? Even one? I can think of multiple times where that is explicitly stated for Orihime and one time where it's explicitly stated for Renji (albeit somewhat vague with the whole "getting us back together" comment).
So it's:
Ichigo x Rukia: Gazing at each other eyes a few times, some camaraderie before Hueco Mundo arc when Rukia gets demoted in terms of relevance.
Ichigo x Orihime: Gazing at each others eyes a few times, camaraderie throughout the entire series, multiple confirmations of love from Orihime, and an explicit confession from Orihime.
Renji x Rukia: Gazing at each other eyes, camaraderie from Hueco Mundo arc to final story arc, explicit relationship ("getting us back together" comment).
Ishida x Orihime: Pure headcanon
That's how I see things. And I again. I don't think it's well written. I don't think anything post-soul society is well written. That being said, there were solid clues to let us know it was gonna happen. Nothing like the Naruto ending.
If this series were to have stopped at Soul Society, I'd see where you were coming from. But we get some things in Hueco Mundo and the 1000 war arc that more or less seal the deal.
Also, just because Orihime loved Ichigo means that he's obligated to love her back? There was nothing from him, nor from Rukia in regards to Renji, that even suggested that they had feelings for their partners. Renji's comment had nothing to do with romance, it was all about how he felt a debt to Ichigo because before Ichigo beat his ass, Renji and Rukia hadn't talked for half a century. Renji was even ready to watch her die without a care in the world, because of spite.
Undeveloped is an understatement for those ships.
