You were just trying to save a certain black cat from getting tortured from these cruel "wannabe bad boys" that were playing too roughly with the cat. A blonde boy in a uniform shouted from behind, he look quite upset when he saw them picking on someone and he grew more upset when he saw his cat peke J getting involved in the situation. He didn't hesitate to beat them up as they all fall into ground unconscious.
"Thanks for protecting my cat. "
He bowed his head in a respectful manner.
