I dreeeam with a beautiful poliamory fanfic with this scene. I have started writing, indeed ( ꈍᴗꈍ) LOL. Misaki just can't help how much she loves those two. and Mikoto and Junko are beautiful nice friends that respect and care for each other (˘︶˘).。*♡
@BV you've probably seen it elsewhere. This image has been around since early 2014 according to the artist's pixiv: https://www.pixiv.net/en/artworks/42543904
They only just recently (June 2020) posted (or maybe reuploaded) it to their twitter where the source link leads to.
I'm not opposed to rediscovering this absolutely wonderful art though. It deserves the attention.
