let's clarify!SADNESS is hugging; not Anger, because Anger isn't a hugger. There's no "they", there's only "she".And for whatever the reason she has for hugging Anger he seems to accept it (just don't expect him to hug back)There's no story to it, I just drew it like a moment they could've shared at some point. Most of my other drawings are like so.The creators mentioned that they wanted the emotions to stand out abit human, so sadness CAN feel joyful and Disgust CAN fell scared and anger CAN feel sad and etc.They just normally act acording to the emotions they are themselfs (which makes sense)In this moment there's abit of joy between the two characters.
