It was Harry's fourth year of nice, normal Hogwarts. He'd had a nice life at Hogwarts. He was always the hero, he'd slaughtered Voldemort and he hasn't returned since. Harry's life was pretty good, all things considered. Only problem was, his DADA professors were always a bunch of old, boring dozes and Harry wasn't expecting it to be any different this year. He'd be bored stiff which meant he'd probably make the teachers life harder than it had to be but oh well, who really cares about teachers anyway? 

Before he knew it, he was on his way to the first DADA lesson of the year. He was walking as slowly as he could just so he could waste some time, after all, he did know all this crap already and if he didn't, he'd just make some nerd do it for him. Like that Granger.  

When Harry got to class he was surprised to see he was the first one there and even more surprised to see the hottest man he'd ever seen. James Charles. Harry was a big fan of his WizTube videos, such a big fan in fact that he began violently fan-girling right in front of JC, the man himself!

Harry managed to compose himself just before James Turned around. 

"OH, hey sister!! So I'm your new DADA teacher. You can call me da-" he stopped and  cleared his throat, regaining his professional stance. "..you can call me Sir Charles, Professor JC or Professor Charles."

"umm okay." Harry said before breathlessly taking a seat right at the front of the class, as close to James's desk as he could get. Then, one by one the rest of the class started piling in. Harry doesn't remember anything after that. All that mattered was James and his inviting scent. By the end of the class, it's fair to say Harry was sister shook.
