You must know, now that the Captain has insulted Ali's dignity in front of so many people, Ali surprisingly doesn't seem unhappy at all and even smiles. You should know, that smile isn't due to bitterness after being bullied, but rather a smile of inevitability.
This is because the Captain's noble status is higher than Ali's. To Ali's mind, it's only natural for the Captain to bully him, so there's nothing strange about it, and that's why he doesn't feel any unhappiness.
This is servility, long-term servility. Even Ali, who is a high-ranking noble in D country, is the same when he encounters a captain of higher nobility than himself.
Ali still has this servility, and it is something that cannot be changed. This is also the sorrow of a nation.
In D country, such occurrences are quite common and frequent. Some of the poorest in D country even spend their days prostrate, allowing the noble aristocrats to walk over them, leaving noble footprints on their bodies.
