you're in a really bad mood because your parents fought again last night and they took it all out on you. you felt really tired so at school, you didn't even interact with anyone. including your best friend, Shu. He would try and talk to you but you kept ignoring him. So, when the classroom is empty while you're packing up your things, Shu suddenly snapped.

"That's it! what's wrong with you? you've been ignoring everyone all day! ... you know i hate it when you do that.."
