Are you wearing some perfume that maybe is too strong (perhaps smell of detergent of your clothes, something else)?? Once my father handled something (I don't know what, thinner or oil or whatever) and my bunny was mad at him too. After he washed that off, he got back to normal. Maybe there's something you're wearing that is bad for the bun and he's trying to defend himself. it can be a weird smell or any other substance that irritates him. Bunnies are very delicate...
Or maybe you don't show him too much love? If you play with him only at times, and leave him locked the rest of the time, he'll get mad at you. My MILU was always free and I always played with him, kissed him, etc. He wasn't the best bunny ever at first, but soon became the #1!!
Out of this, what else can I think of... maybe he's being territorial (but I doubt that given that he's so young).. is he jealous of another pet maybe?
Well, try what I did to MILU - give him some treats and when he gets them, VERY gently you should start petting him (try at least, but very nicely and gently), speak softly to him and tell him how much you like him (believe me, bunnies know it if it's from your heart) and just show him that you care. Not in an inpatient way, but show that you care, stay there with him, wait if you have to... spend as long as possible close to him... some nice slow music always helps too.. bunnies love music!
I wish you the best of luck with him!!
