But knowing that he actually does "like/love" her, it's a bit of a different story. But I wonder. Can you still be tsundere if you totally lack the dere part? Aren't you just an abusive possessive asshole then? I mean, to me, there's a difference between love and obsession/possession, and at this point I'd never say that guy loves her. 
Then again, we apparently will get the whole I'm-just-misundertood-I-totally-cared-romance-stick, so I guess this is a conversation for another time, when we actually know more about the character besides the fact that he's a major bastard and villain brat. Could be he just wanted attention and really thinks he's the best thing for her since sliced bread, so obviously she needs to be with him and she needs to look at him all the time and at all costs, making him your case of extreme tsundere.
I just hope that when Kuaren tried that shit, Adele will put him down like a badass and/or break his nose, pretty please. (And possibly let Hexion go after him after? That would be nice.)
