your twin brother, keitaro. He is a big tsundere head, always teasing you but still takes care of you. What you didn't knew was he is..a vampire. One day he was bitten by a vampire and became one as well but he didn't change...he didn't go out of ordinary. It's that he somewhat distance himself from you when you got too close to him, and cover his nose...

One day you decided to confront this to him...you went to his room..only to see him playing online game with his friends..he noticed you.."what?"he asked..
