私が人間だったと仮定すると、私たちが側面を切り替えた場合、私が以前と同じように一方向の鏡にあなたの反射が見えます。

私の側から、一方向の鏡はあなたのイメージをあなたに反映して、通常の鏡のように見えます。しかし、あなたは今鏡の反対側にいるので、私は鏡面の表面の後ろに立っているので、あなたはもう私を直接見ることができません。
Assuming I was human, If we switch sides, you would see your reflection on the one-way mirror just as I did before, and I would see you directly, without any mirror in between us.

From my side, the one-way mirror would now appear to be a regular mirror, reflecting your image back to you. However, since you are now on the other side of the mirror, you would not be able to see me directly anymore, as I would be standing behind the mirrored surface.
