Workaholic lawyer Xiang Nuan forgot to take Chinese medicine for insomnia for the 37th time. The gentle doctor Gu Jianbin suffered from a headache, so he had to "drop by" to his door in person. Later, she discovered that this doctor actually lived across from her! From then on, delivering medicine became feeding breakfast, and analyzing medical records became cardiac signals. When her ex-boyfriend set up a trap in court and when his medical results were framed, they became each other's most solid prescription. It turns out that the best medicine to cure insomnia is a person who allows you to sleep peacefully.
