My bunny seems sad? ):?

My bunny Daisy. She is a female mini lop and she is about 5 months old. She has a playmate Peter. Who is a male but is also a mini lop who is about 4 months old. They are in the same cage, the cuddle and get along. She just seems sad though. When ever it comes to her being in contact with me or anyone else, she runs into the little hut in their cage or she tries to hid somewhere. She will take treats out of my hand but doesn't like it when I touch her. Peter on the other hand is the complete opposite. He gives me kisses and hops around everywhere and loves attention. Is something wrong with Daisy? ):
