Nicknames can only be used between lovers and family. Using them otherwise is a clear insult. Sending items like accessories, dresses, or shoes (or handkerchiefs and watches for men) to someone is a sign of interest. If a young lord adds 'Lady' or 'Mademoiselle' after a request to a young lady, it is effectively a confession. Adding complimentary adjectives (beautiful, radiant, jewel-like, etc.) before 'Lady' or 'Mademoiselle' is essentially a public confession.

Stepping on someone's foot on purpose while dancing is a way to signal 'I dislike you' in social circles.

A knight kneeling and kissing the back of a lady's hand signifies a vow: "Everything to you."
A male noble kissing the back of a female noble's hand with one hand behind his back is a polite greeting, but doing so without putting his hand behind his back is a courtship gesture.

A male noble gently holding a lock of a female noble's hair and smelling its scent signifies interest and asks, "Where are you going?"

A noblewoman or young lady intentionally dropping a fan or handkerchief while passing a male noble signifies interest. If the male noble picks it up and returns it, it is a gesture of acceptance.

Crimes such as blasphemy, insulting the Magic Tower, treason, or defamation of the Imperial Family are subject to summary execution on the spot.

Even the Emperor must not address a young lady or lord using informal second-person pronouns like 'ya' or 'neo'; they should use 'thou,' 'young lord,' 'young lady,' or 'Lady.' The first-person pronoun should be 'We' or 'This One.'

Regardless of rank, one must not openly insult those of lower status. Criminals are an exception. If a noble house passes its title to an illegitimate child due to circumstances, that child assumes the full status of the title received.
