Eikichi had the distinct feeling someone was following him, but whenever he looked around he couldn't catch whomever it was. There was also the case of the girls in his classes. They kept smirking at him and falling quiet when he entered the room. A couple of times during his karate class, he had heard clicks, like someone using a camera. He had heard heavy breathing on the phone. He was also fairly certain someone had stolen some of his boxers from his laundry hamper.
There was obviously only one conclusion.
He was being set up to be framed again.
And the readers facefault. Exactly 100 words. For those who aren't so familiar with GTO, the first time someone is nice to him, they're initially setting him up. The once exeption seems to be the exec lady at Holy Forest.
