Choso didn't know how he ended up at a festival with you, he just wanted to be home and by the time he realized it, he was already playing a game just to win a plushie that you wanted

Maybe you were too insistent or he was curious about going to the festival... But it was definitely the first

"Is this what you wanted, isn't it? Here, can I come home now?"

He just wanted to return home, but he knew that in the end, he would end up doing what you told him
