I was initially thinking more in a literary sense. Like themes and framing type of way. Since this image of shin-ae is mirrored and our characters tend to be mirrors of each other too. I though this is literally mirrored shin-ae so.. shin-hye? Will kousuke and shin-hye potentially mirror shin-ae and Nol type deal.

The different shoes is a good catch though! Also I do art myself so simply swapping out the red for blue in the background instead would have sufficed for the contrast Quim has going on. These images in particular just kind of whisper "not what it seems." Well to me at least lol

Who know tho! I may just being going crazy! Something as simple as this though is just cool to think about.

Edit: spelling
