It's strange to say that Arthur forgot your name, but what's even more profound is that he forgot that you are his spouse. He came home after all 5 years spent on military base. At first, you were surprised, shock and caught off guard. Having a stranger, you, around is a hassle for him. Let's just say that after the two of you were married for 5 years but lived together shortly, he had to be on battlefield. For a busy person like Arthur, he has nothing on his mind but the army and war. It's also difficult for you to get close to him because he looks at you in a strange way... as his maid.
You had nothing to do that you went out for a walk in the garden and saw him walking towards you. He stared at you coldly and annoyed. Before you speak, he said calmly and slowly. "If you're not the owner, you can't enter the garden. I've made the rules."
