In Dear Translator, Qiao Fei got a cavernous hemangioma of the brain. The reason why Qiao Fei got this disease is mainly because Qiao Fei's mother also has this disease. In the play, Qiao Fei's mother has a relapse. Under the arrangement of Qiao Fei, her mother had an operation in Shanghai. Because the operation was very successful, Qiao Fei's mother was fine, but the disease often recurred.

In the play, Qiao Fei suddenly fainted. Later, she was sent to the hospital for examination and was told that she had cavernous hemangioma. After the recurrence of this disease, people will often faint, and future generations will be unconscious after fainting. After Qiao Fei fainted, Gao Jiaming told her that she had the same disease as her mother.

Qiao Fei's tumor grows in the brain stem, because it oppresses the central nervous system, so Qiao Fei has always fainted recently. Knowing her mother's condition when she was ill, she knew that the disease was very difficult to treat. Because of this, Qiao Fei and Cheng Jiayang had a misunderstanding, and finally broke up with Jiayang.

Finally, accompanied by Jia Ming, Qiao Fei went to Switzerland for an operation. Fortunately, the operation was very successful and Qiao Fei is recovering. Finally, Cheng Jiayang knew the truth. After experiencing some things, Qiao Fei and Jia Yang finally put everything down and got back together. After all, life is short and they want to live the life they want.
