Lu Jiao's first reaction was to decline.
However, she quickly thought of how much people during this era cared about ceremonial formalities. Ceremonies made things official to people and would make everyone aware of the fact that Qi Lei was her apprentice. They wouldn't gossip once they know.
If the apprenticeship becomes official, nobody would gossip. Because the relationship between a master and an apprentice was the same as the relationship between a father and a son.
Lu Jiao asked, "Is your family okay with you being my apprentice?"
She knew Qi Lei was from the capital city and was from a good family. Would his family be okay with him having such a young woman for a master.
There was no such thing as equality in this era and she didn't want any trouble.
