Heresy!
I see the appeals of an Ami-Hazou relationship, tbh. My primary concern is simply that Ami keeps a romantic contextualization/framing on her dyamnic with Hazou because it's safer/more familiar to her than a platonic, emotionally intimidate friendship/familial dynamic.
That, rather than genuinely feeling romantic feelings for Hazou, Ami artificially (though, perhaps subconsciously) directs herself in that direction because, as an I&S jonin, romance is where she's more capable, more at ease, and more in control of the situation. Ami's flat-out admitted on-screen that she doesn't know what a genuine family feels like, after all. But romance? Ami knows romance.
