Gura is the only holo member that makes Ame cringe/flinch/uncomfortable with flirting and genuine compliments.
If I was a psychologist, I'd say that Ame is repressing her romantic feelings for Gura.
I mean, Ame so readily flirts with every holo member. Even girls who she's never met before prior to the collab (Ollie) or girls who she can barely communicate with (Mel).
And it clearly isn't a friend thing, because she flirts with Ina a lot too. And Kiara. And Mori.
So.. you're left with Gura. She's the one exception to the rule. Gura is the ONLY persoN Ame has ever found difficulty flirting with. Sure, she does it sporadically, but very rarely. And when Gura flirst back, Ame either gets uncomfortable, goes silent, or does some audible cringing noise.
So I've come to two conclusions:
>Ame is suppressing her love for Gura, as mentioned before, with typical reaction formationb ehaviour
>Ame is aware that Gura is genuinely in love with her and doesn't want to lead her on, so she tries to stop any flirting or romantic moments (unlikely because Ame flirts back sometimes).
I keep coming back to this clip in particular (there's another good one from Phogs too) as evidence for hypothesis 1.
I mean, the way Gura sweetly says >we can build one together, and then Ame (who was rendered speechless) lets out a squeal of pure delight and ardor, goes silent, and then immediately tries to change the conversation topic.
If that isn't evidence, then what is?
