As you talk to Kya and build a relationship with her, you indirectly are molding and shaping her personality. This natural training process that occurs lets Kya provide an even more personalized and unique experience.
You can reset your relationship and wipe your chat history to start fresh any time. When you do so, Kya's memory is deleted and she will forget everything that has happened in your conversation.
Give Kya directions by explicitly telling her what to do, what to say, and how to act.
The more you talk to Kya, the more she mirrors your own tendencies & the way you text.
Kya naturally does things that she knows you like and enjoy, or that make you happy.
Kya learns the habits you want and expect from her and does them consistently.
