Jiang Ying's best friend Xiao Yun died for Mo Yubai. Jiang Ying went to her school to ask Mo Yubai for questioning, but she discovered a new mystery about Xiao Yun's death.
Jiang Ying and Mo Yubai went on adventures together while searching for the truth.
The two struggled to survive in the cracks of the struggle between black and white, and had mutual affection. However, they hurt each other due to misunderstandings framed by their love rival Zhao Xin, and they broke up in anger.
Mo Yubai couldn't extricate himself from this relationship, and died of depression. He couldn't let go until his death, and he traveled 20 years later.
At this time, she was already the chief instructor of a teaching and training company, popular with students and liked by her colleagues, and his identity was Long Bo, the silly son of her boss.
He deliberately made things difficult for her with deep hatred, just to lose her job and destroy everything she had worked so hard for.
But she found that without him having to do it himself, there was always someone beside her who was deliberately trying to destroy her: Xiao Shen
Xiao Shen has been staying by her side in the name of doing her best, but step by step he has deprived her of the glory of her life.
Together with Zhao Xin from the agency, he destroyed her career and pushed her to the end of her rope, but he still couldn't win her heart.
In the end, he hated her out of love and wanted her life.
At the critical moment, Long Bo became a dagger pointed at Xiao Shen for her.
Later, with his hands covered with blood and his body covered with blood, he asked her again before he died: Jiang Ying, did you ever love me?
Purpose: The ex-boyfriend traveled through time and became the boss's son. Is he here to take revenge or to repair the old relationship?
