@REDflame23 - Since whoever uploads the images has a habit of always putting a Watamote image last, I don't really believe that you would have been able to tell who they were with zero context.
^^Possibly tho if so, that means it might not even be yuri. (Twins doesn't rule it out ofcourse but twins may well just sleep while hugging like that without yuri too).
I need to ask, why the incredible amount of It's Not My Fault That I'm Not Popular! things this last months? The serie started in 2011, 8 years ago (?)
