Who are these two people on the placeholder's cover?

I would like to know too(づ￣ ³￣)づ

I don’t think anyone knows but if I find out the name I’ll let you (っ◞‸◟ c)

i have also been dying to know DDDDD:

i reverse image searched it and it didn't yield a lot -- mostly broken twitter links..

i found this one link to a novel, i believe they are using the image as a cover but i don't know if it's related to the actual story :(

so i truly don't know.. possibly just fanart and we'll have to live with it just existing in a singular form ┗( T﹏T )┛
