Luo Ning had agreed to go to the Luo Family only after seeing the message hidden within the lobster.
Today, after receiving the seafood, Lei Qiu told her that his dad had said she'd best deal with the largest lobster right away, or it wouldn't be fresh or tasty.
Luo Ning felt there was a deeper meaning to these words, so she decided to slice open the largest lobster.
It was inside the belly of the lobster that she found this wad of paper.
The writing on the paper was not only in her dad's handwriting but also carried his scent, proving it wasn't an imitation.
A father knows his children best; Old Man Luo knew that her dad considered her and her mother as his weaknesses.
And a child knows their father just as well; her dad must have known that Old Man Luo himself had come to the Imperial Capital and guessed what he was planning, hence he had used Old Lei to send this message.
