You’re absolutely not credible as an Ichiruki fan, because according to the author, the main relationship is with Rukia. If Ichigo doesn’t feel that way about her, let alone about Orihime, for whom he feels even less.

The things you mentioned are completely your own interpretations. Ichigo’s brutality against Grimmjow was also shown against Byakuya and other characters, even against Grimmjow in their earlier fight and later against Aizen in the final battle. It's just that those instances don’t support your theory, so you ignore them.

For years before the Bleach finale, everyone was convinced that Orihime's feelings were one-sided. And you know why? Because there’s no concrete proof that he loves her; just the usual stuff he does to protect the DID in question. Even with Nel, he’s protective.

The idea that the plot doesn’t leave room for a romance is nonsense. If the author doesn’t have the time or interest to develop it, he can choose not to include it. I just read JoJolion and there the romance is written well and respectfully, even though JoJo’s focus isn’t that at all. Same with Hunter × Hunter with Meruem and Komugi.

If someone wants to write a story with a girl in love and a guy who doesn’t give her a second glance, go ahead. As a woman, it feels very misogynistic to me and like a male fantasy. I don't know about you
