If the Scott family had guests to stay overnight, under normal circumstances, they would be arranged in another building.
Only distinguished guests would be arranged in the Scott family's castle, and some long-term important guests would have their own exclusive rooms.
When Boris was arranged to stay in the castle, she didn't think it was strange.
Because although they were divorced, he was still Ewen's biological father, and that fact would never change.
She didn't plan to hide it from Ewen. She thought that when Ewen grew up, she would tell him that his father was Boris.
As for how Ewen would get along with Boris, it was up to Ewen.
Therefore, she thought it was normal to have Boris stay there.
She basically didn't go to the floors where other distinguished guests were staying, nor did she ever come and find Boris.
So, why did he have this hook on his door?
Who stuck it on?
