>>44367638EXCUSE ME, I am a professional Guramefag and the first moment you cited is UNAMBIGUOUSLY a GURAME MOMENT.
What you have failed to notice in your oblivious and misguided rainforestfagging is that Gura was the first to intentionally go out of sync being the shitty brat that she is, starting at this timestamp
https://youtu.be/da26TN6N7E0?t=3036Next you see Ame look over to the left, not at Mori, BUT AT GURA, and then she adjusts her swaying to MATCH GURA, proof:
Right here, as Ame is looking to the left, she also begins to sway to the left to continue matching the rest of myth, but she stops when she sees Gura
https://youtu.be/da26TN6N7E0?t=3039Then, right as Gura hits the apex of her rightward sway, YOU CAN SEE AME TILT TO THE RIGHT TO MATCH HER
https://youtu.be/da26TN6N7E0?t=3040THEN WHEN THEY BOTH REACH THE LEFT SIDE, AME KEEPS LOOKING AT HER AND WAITS UNTIL GURA BEGINS SWAYING TO THE RIGHT AGAIN
https://youtu.be/da26TN6N7E0?t=3041and THAT'S NOT ALL
You can see Ame turn away from Gura to look out at space, but then Gura swings back to the right faster than Ame expected
https://youtu.be/da26TN6N7E0?t=3045YOU CAN SEE AME QUICKLY LEAN TO THE RIGHT TO MATCH GURA AGAIN AS SHE LOOKS BACK AT HER
