When Jiuxiang was seventeen, she came to England to study alone. When she was eighteen years old, she wrote a love letter, which was childish and ridiculous - that love letter was written to a boy who didn't love Jiuxiang.
As a girl, Jiuxiang is such a failure. Later, when she became a woman, she suddenly became popular. All in all, Kenan was the only man who truly loved her during her girlhood. So she must let him turn herself into a woman.
Kenan loved her with all his heart and did not allow her to be hurt in the slightest. Including their sexuality. He always puts her happiness first - he is afraid of her getting pregnant and never dares to get complete satisfaction from her.
Jiuxiang, who has just become a woman from a girl, does not understand this kind of love at all. She feels that this kind of love is incomplete and thinks that Kenan has a physical defect.
Just after the two got engaged, another situation suddenly appeared...
