Before Reincarnation
Before reincarnating as Katarina, she (name not mentioned yet) was a 17 year old high school student. Her family consisted of a mother who was a part-time housewife, a typical salaryman father, and two older brothers. She was commonly called by her classmates as 'monkey', due to her quirk of randomly climbing trees. She was usually scolded by her teachers because she would regularly forget her homework. Because of this, she would always ask for help from A-chan, her best friend.

After Reincarnation
Katarina Claes, before remembering her past as a high school student, was arrogant and possessive of Prince Gerald. Her memories resurfaced after she hit her head on the rock which changed the attitude of the real Katarina.

Prince Gerald
In the game, Fortune Lovers, Prince Gerald has no love with the game Katarina and mainly uses her as a shield so that other women would avoid making any attempts to grab his attention. Currently, Gerald has genuine romantic feelings for the current Katarina, who is oblivious of Gerald's love towards her and only believes that Gerald is simply using her to lower any unnecessary attention from other noble women, and Gerald refuses to annul their marriage despite how certain people, like Keith and Katarina's mother, are now opposed to the marriage as Katarina was not suited to be a princess.

Keith Claes
In the game, Fortune Lovers, Katarina and Keith were supposed to have a cold relationship. Because the current Katarina was able to prevent Keith from being lonely, their relationship is considered very positive. Unbeknownst to Katarina, instead of being a playboy like his game version, Keith had become a sis-con who is completely infatuated Katarina and sees other people, like Gerald, as rivals. Keith is constantly worried about his sister, who is oblivious of how many people she unintentionally seduce.

Duchess Claes
The mother of Katarina, who was initially happy about Katarina's engagement to a prince. However, due to how Katarina later begins to develop an eccentric behavior, such as farming and tree climbing, Katarina's mother wishes to annul her daughter's engagement, believing she is not suitable to be a princess and bring shame to the family. Katarina's overall relationship with her mother may be considered somewhat negative, as Katarina would very much wish to avoid meeting her mother, it wasn't considered abusive.
