@suzy As someone who's reading it presently. Her personality has always been like this, she's strong, sassy and bossy most of the time but when it comes to matters of her reincarnation and family, she becomes fretful and anxious because she had a lonely life as Yoon Ji Yoon and had a horrible father in her earlier years, so at first she couldn't bring herself to fully trust them but as she continued being with them that changed and she started to ove and care for them as her own family, but still kept her boundary because she felt like she was stealing the actual Soleia's life. So, as a sort of self-atonement she decided to protect her father and brothers in place of Soleia who's body she took over; She hasn't fully accepted this body as her new life so she'll feel guilty if anything happens to the family who gave her so much love and patience, Soleia's family.
