After living for 21 years, Zhou Xilan has never had feelings for any boy. She once thought she liked girls, so she even tried it on her best friend, and finally concluded that she was not interested in girls either.
But there was one exception, but Zhou Xilan never thought that he would have feelings for her. He only thought that she had a good personality and good teaching methods, nothing else, just because that person was Zhou Xilan's teacher.
That teacher went abroad when Zhou Xilan graduated from high school three years ago. She didn't come back for three years. Once she came back, she showed up at the class reunion.
At the class reunion, Zhou Xilan, who always drank well, passed out after just two drinks. When he woke up, he found that he was back in high school and was passively bound to a system. Zhou Xilan, who was confused, could only hear two words clearly after the system talked about it, Gu Zinan and the system.
Zhou Xilan wanted to ask, but the system disappeared.
In the boring high school life, apart from a few friends, the only thing Zhou Xilan can miss is her English teacher. On the first day of school, Zhou Xilan, who was sitting in her seat waiting around, didn't even wait for her teacher Gu Zinan, but instead waited for a girly version of her classmate Gu Zinan.
In this way, Zhou Xilan began a different high school career with her former teacher as her deskmate...
Everything was calm until the end of the first year of high school, and the system never appeared again.
But what Zhou Xilan didn't expect was that the system appeared again when Gu Zinan was about to die.
Only then did Zhou Xilan realize that she had a mission. She had three chances to save Gu Zinan. If she failed three times, the mission target would die and she would return to the real world... But in reality, Gu Zinan had already suffered from cancer.
The second time around, Zhou Xilan began to take it seriously and stayed by Gu Zinan's side almost inseparably, but there seemed to be a force blocking them secretly...
Once again, Zhou Xilan watched Gu Zinan die in front of him...
Purpose: "Plant flowers in your heart, and your life will not be barren."
