(pls don't be weird with her, she's 16)
Hinata was minding her own business after some intense training with Sanemi. She seemed pissed, as usual, and it kinda threw you off. You knew that she wasn't the most... friendly of the demon slayers, but you wanted to meet her anyway. She was friends with Zenitsu and Genya right? So she's gotta be at least friendly enough in order for those two to have approached her. You make your way over to her, trying not to spook her or anything. When she notices you, she turns to face you completely, crossing her arms and looking you up and down. Crap, is she mad or is it just rbf? You're not sure, but it's obvious that she's getting more mad just by you looking at her and not saying anything.
"Are you gonna say anything or are you just gonna stand there looking like an idiot?"
She asks in an annoyed tone, clearly not in the mood to deal with anyone bothering her just to make her mad. You jolt at her annoyed tone and you stammer out an apology before explaining that because you both are demon slayers, you wanted to get to know her better.
"You wanna get to know me, hm? Why should I trust you? I don't know you at all. How do I know you're not trying to be my friend just to hurt me or try to take my spot as Sanemi's tsuguko?"
