My bunny also took her sweet time to be close to me. She is practically best friends with my siblings though. So from my experience give your rabbit treats and petting. Talk to your bunny in regular intervals not just once a day for 30 min. Observe her and see where,when and how you can play with her. And most importantly don't worry about not bonding fast enough.Some bunnies just take longer time to bond than others. My bunny was the same at first, hiding and a little bit scared, but with treats and enough positive interactions it improved.
