I wanted to draw two of my sonas interacting with each other, so why not the two lonely losers comforting each other and talking about their sad lives?
Happy (the green thing) has trouble keeping relationships because he fears he'll become too attatched and he'll get himself hurt. He never really commits to a friendship or any other relationship.
Castiel (tiger with antlers) has trauma from bullying in his past, so he lives alone on top of a mountain with a bunch of pigeons.
Neither of them really know how to interact with people, but they know how to hang out with each other and take care of each other. That is... if they ever met in the first place... oh well, this drawing was just to give these two sonas something nice, even though they'd probably never meet.
