On an ordinary day, Lin Beixing accidentally dug out an old mobile phone that had been gathering dust for a long time.When she turned on the phone, she was shocked by a sudden text message.The content of the text message is simple and mysterious: “You have a chance to go back to the past.”Lin Beixing's heartbeat accelerated instantly. She knew that this was an opportunity to change her destiny.

Taking a deep breath, Lin Beixing decided to go back to the past with the help of this old mobile phone.When she opened her eyes again, she found that she was back in her senior year of high school.At that moment, her heart was filled with excitement and anticipation, because she knew that this time, she had the chance to change everything.

Lin Beixing's goal is clear: she wants to transfer to Zhang Wansen's class.Zhang Wansen, the name she could never forget in her heart, the boy who met with misfortune after the college entrance examination.Lin Beixing knew that if he could get to know him earlier, he might be able to change his destiny.

However, things did not go as smoothly as Lin Beixing imagined.When she expressed her wishes to Zhang Wansen, Zhang Wansen avoided the sudden appearance of the girl.Lin Beixing felt confused and lost, but she did not give up.She began to investigate Zhang Wansen's situation, hoping to find a way to get close to him.

After some investigation, Lin Beixing discovered a surprising secret: Zhang Wansen had been bullied by a “red-haired gangster”.This gangster was domineering in the school, and he was even more aggressive towards Zhang Wansen.Lin Beixing deeply felt that Zhang Wansen's accident after the college entrance examination was inevitably related to this gangster.

In order to protect Zhang Wansen, Lin Beixing decided to step forward.She is no longer a bystander but a brave warrior.She began to plan how to help Zhang Wansen get rid of the entanglement of gangsters, and at the same time, she also worked hard to establish a deep friendship with Zhang Wansen.

Lin Beixing's actions gradually attracted Zhang Wansen's attention.He began to become interested in the girl who had been guarding him.As time passed, the relationship between the two gradually heated up, and Zhang Wansen also began to open his heart to Lin Beixing.

The college entrance examination is approaching day by day, and the relationship between Lin Beixing and Zhang Wansen is getting better and better.However, the red-haired gangster did not give up harassing Zhang Wansen.In an unexpected conflict, Lin Beixing was unfortunately injured while protecting Zhang Wansen.

This incident deeply touched Zhang Wansen.He finally understood Lin Beixing's good intentions and selfless dedication.With the encouragement and company of Zhang Wansen, Lin Beixing gradually recovered, and their relationship became deeper.

The college entrance examination came as scheduled, and Zhang Wansen performed his best with the company and encouragement of Lin Beixing.In the end, he successfully entered the university of his choice, and Lin Beixing also successfully completed his mission.

Lin Beixing, who returned to reality, was filled with emotion and satisfaction.She knew that although she couldn't change everything in the past, she could at least secure a better future for Zhang Wansen.
