In the modern days, Gu Xijiu also had dysmenorrhea. When she started to study medicine, the first thing she learned was to overcome dysmenorrhea, so she was an expert in this treatment.
When the doctor arrived with Yan Chen, Lan Waihu was not in pain anymore. She also knew how to handle it under the guidance of Gu Xijiu.
After this incident, Lan Waihu totally changed her attitude to Gu Xijiu. She followed her like a little sister and whenever she saw Gu Xijiu, she would smile happily like a sunflower.
Of course, Yan Che who still took precautions against Gu Xijiu was not happy when he saw his hometown mate following Gu Xijiu often. He once called Lan Waihu out and scolded her for a long time, but Lan Waihu who used to always listen to him had refused to listen to him this time round.
