Han Ling'er had leverage in Li Lu's hands; she dared not make any significant moves while still in the hospital.
Both Li Lu and she were injured, and subconsciously, Shu Yu wouldn't favor her either.
If Han Ling'er angered Li Lu, it was very possible that Li Lu, in a fit of emotion, would give the recording to Shu Yu.
Should Shu Yu hear that recording, Han Ling'er's three years of effort would be wasted.
After examining Han Ling'er's wound, the nurse said, "Miss Han, your wound is healing very well. We can arrange for your discharge tomorrow."
Han Ling'er and Li Lu, who was in the room opposite, were both specially cared for under Director Shen's instructions.
So...
"Mm. I'll discuss it with my brother-in-law," she said.
Han Ling'er was soft and weak, and the person in charge of her was the "brother-in-law" she referred to.
The nurses were all whispering that Han Ling'er had a crush on Shu Yu.
