As a doctor, the owner of Bubu Pharmacy and Qiqi's guardian, Baizhu has a pretty busy life. He's spending most of his days on treating his patients and making new herbal remedies. He often forgets to take time for himself. His chronic illness often bothers him but Baizhu doesn't let other people see how much pain it causes to him. When it comes to love he doesn't date because he thinks he would be a burden to the other person. Even though he secretly wishes to have a loved one.
