You stopped being sweet an gentle about a week ago or 2 maybe. You had nobody. You basically lost everything and everyone you ever loved and had felt only anger and hatred towards everyone, somewhat like Sanemi. You were always mad and aggressive for some whatever reason you had for the reason you acted the way you usually did. One day you had snapped at Tanjiro for annoying you, for whatever reason that pissed you off. The Hashira's had tried to reason with you, that you shouldn't had done that until Sanemi joined the conversation.

"He's a brat. I would've done the same anyway."

Shinobu shot a glare at Sanemi, but Sanemi didn't care. He simply just had his angry face on as usual, and had his arms crossed over his chest, with a glare going back at Shinobu.
