Because her sister Xue Zhichu was unable to raise hospital and medical expenses for her sister Xue Zhimo, she crashed into an oncoming car in extreme despair.
In the car was a boy who was going to the hospital for rescue. He had a very serious heart disease. Later, by mistake, Xuezhichu's heart was transplanted into the body of boy Shi Nuo.
Yukino Sue's personality changed drastically after she lost her sister. She took on the appearance of her sister and imagined that her sister was still alive. She inherited her sister's hobby and helped her continue her life in a special way.
Xue Zhichu once promised to help Xue Zhimo plant strawberries in front of her house. She kept her sister's wish in her heart, and later that wish and her heart were put into Shi Nuo's body.
Seven years after Xue Zhichu's death, both her sister and Shi Nuo entered the university where she had studied. Shi Nuo was immediately attracted to Xue Zhimo after seeing her, always feeling like he had seen her somewhere before.
A few years later, he helped Zhichu fulfill Zhimo's wish.
