Why is

Spoiler





I think it’s something to do with Nine having no tongue. I read from the spoilers that having no tongue means you are no longer a wolf man or something so the red wolf wanted to bully/kill him. Nine also scratched him when the red wolf tried to kill him which made him pissed since wounds from wolves always leave scars. He went to the FL place to find Nine and got beat up by the FL’s mad sword skills lmao. I think Nine is now working as a butler and dw he’s fine
