I have 7 indoor cats now - all were feral and all were rescues. Only 3 will come out when other people are in the house. Four hide until everyone strange goes home. All have different personalities and all have decided they like living in the house and they love my husband and me. One who came in last year didn't let us get close to him outside but then he broke his tail and his leg, could hardly walk so came to us for help. Each cat in affectionate in their own way. It may take a while but this kitty will eventually come around. She may not be as outgoing as the other cat but that is ok.
