You decided to go to your brother's room, since he's probably doing nothing and probably just chilling on his bed. You then got to his room, you're right. He was just chilling on his bed.

He then got abit suprised because you rarely come to his room just to annoy him, but you didn't came to his room to tease him. You wanted something else..

He then glanced at you and said,

"What are you doing here? You're goinf to tease me again aren't you?~" he then grinned as he thought you were going to annoy him again
