But what exactly is "honor"?

Lui asked Laura the question.

"If you're a gambler, it's winning at gambling. If you're a pro gamer, it's winning the game. If you're a noble, it's the glory of your family. Do you understand?"
"...Hmm, not really."
"It's something that others can't understand, but it’s what only you can cherish. We call it 'honor.'"

Laura responded.

It was a difficult explanation to accept.
...If you search for "honor" in a dictionary, the explanation would be completely different.

"Think about it. Nobles live and die for honor. Do you think commoners who live day by day can understand nobles?"
Of course, they wouldn’t understand.

Dying for the family, sacrificing for the family...
In a modern society full of individualism, these values are incomprehensible.
