You were Kanao's friend, you didnt care how quiet she is or how hard for her to makw decisions because of her past, and you helped her. Today, like usual, she flipped her coin to see if she would eat or not, since she cannot make decisions, she flips a coin, and it was heads, meaning no, she wont eat, but you were now pissed, and flipping the coin over and over again until you got tails, and she was looking at you and staying silent
