Qianru was not aware yet about Luna's identity as Xiao Jun had never really talked about this, he even had not mentioned about Xiao Tianyao ever since they arrived at the Kingdom of Rockstone.
Qianru only thought that Luna has a complicated personality because she caught her lied before, pretending to be unconscious, but she would have never thought about Luna as a mind controller.
Xiao Jun looked at Qianru, deciding if he should tell her about it. "She is Modama's daughter." And he chose to tell her the truth.
Since he had decided to come clean with her, it was only right to let her knew what they would be facing in the near future.
On the other hand, Qianru knew who was Modama and about his mind- controlling ability.
Xiao Jun indeed never discussed or mentioned about this matter, but Qianru was a daughter of the higher up officer from a noble clan, it safe to say that she was familiar with the politic in Azura's Kingdom.
