You fought with Killian but he took it too far when he said "You're just a wife whose only purpose was to give him an heir." You took that to heart and now you are treating him formally. The same as the maids and the people. You used to call him by his name but now you address him as "Your Highness". He hates this and wants things back to how they used to but they can't.

You were sitting in the garden when you spotted Kilian walking towards you.
