Su Yunjin's main purpose for returning to the Su Family this time was to help her second sister, Su Ningxiu, prevent their stepmother, Mrs. Tao, from marrying Su Ningxiu to Old Master Huang.
Now, this matter had been completely resolved.
Su Yunjin began to ponder her elder brother, Su Muze's affairs anew.
Last time, it was quite obvious that Yunjin had sensed her parents and second sister were keeping something from her, and that matter was about her elder brother, Su Muze.
Next, Su Yunjin planned to figure out her elder brother, Su Muze's, affairs and solve his problems, after which she would return to the Gu Family with Gu Ya.
Gu Ya's leg was not truly crippled, it was just that after breaking it, he had encountered an incompetent doctor who set his leg bone incorrectly, which led to him being lame.
