At this moment, Shi Su seemed to become somewhat clearer.
Back when she had just escaped abroad, she endured over half a year of nightmare-induced insomnia. Since she was pregnant, she couldn't take any other medication, so the doctor prescribed her this medication that wouldn't harm the baby but could calm her down after waking from nightmares.
She developed a strong dependency on this drug, taking it frequently. Later, the doctor warned her that even if the medication didn't affect the pregnancy, persistent use wouldn't be beneficial for the child.
Therefore, in the two months before the child was born, she tried hard to quit this drug, and it wasn't until after Shi Mianmian was born that her life seemed to be rekindled, and she never touched the drug again.
