When Cheng Le died in an "accident" carefully planned by Qin Haoyu, she finally saw the true face of the people around her - her yandere boyfriend Gu Chuyan, whom she always considered paranoid and clingy, and who even wanted to stay away. In order to protect her, he had already become an enemy of the whole world like crazy, and eventually fell into the abyss with her.
Purpose: Through Cheng Le's transformation from "fearful rejection" to "active approach" to Gu Chuyan, it shows the process of eliminating prejudice and understanding the affection behind other people's behavior, emphasizing that "understanding love" is more important than "getting love".
