That night, Lu Qingfeng was expecting Su Xiaofei to knock on his door. He was still awake despite it being past midnight. Su Xiaofei knew that he had a problem falling asleep at night, and this had persisted until adulthood. His doctor had said that his chronic insomnia might have started after his parents' death, and it only worsened after Su Xiaofei's death.
In her past life, Lu Qingfeng spent sleepless nights in her bedroom after her death, lying on her bed, doing nothing. He would stay like this until sleep caught up with him at four in the morning, only to be forced to wake up at six for work.
As expected, Lu Qingfeng heard three steady knocks on his door, pulling him out from his deep thoughts. He closed the book he was reading and slipped out of the bed to open the door.
