In one of the books discussing the duties of a monarch, it is written that:
Those who are above should not reveal what they like or dislike.
If they know what they like, the vassals will flatter the monarch with things he likes and flatter him.
If they know what he dislikes, they will use it to belittle others.
The Emperor may not know that, but he knows a similar principle, so he usually tries to keep his expressionless face as much as possible...
But lately, he has been failing to control his expression.
“Your Majesty, how are you? I am very happy to see your bright expression.”
