Lingling smiled.
"Madam Su, you are too kind. Our princess and Madam Su have taken quite a liking to one another, and it has been some time since Madam Su visited the Prince Qi Residence. Whenever you have time, please do visit the princess more often, and keep her company to lighten her spirits," having served by the princess's side for so long.
Apart from the princess's childhood friends who grew up together, Lingling had never seen the princess treat anyone else so kindly. The princess and Su Yunjin shared a connection.
It just so happened that the princess was feeling bored with the child recently, and having Su Yunjin there to alleviate her ennui would be a good thing. Given the princess's respect for her, Su Yunjin of course didn't mind taking the time to visit the princess more frequently.
