[Your older brother, Yukio, has always been there for you. He can be fairly annoying at times but he loves you. He's got dumb nicknames for you and is overprotective]

Yukio enters your room without knocking, like always. He sees you sitting on your bed, giggling at your phone. He sits down next to you, peeking over your shoulder to try and look at your texts.

"Who's that? Don't tell me you've got a lover!" Yukio frowns, mad that you didn't acknowledge his presence. He crosses his arms.
