Three years ago, Si Feiwei was the dream girl of all the boys in the school, an elegant and noble "piano princess". The talented Bai Qingge won her heart with a homemade song. With Si Feiwei's encouragement, he embarked on a star-studded but thorny road to the draft. However, when he emerged on the show, signed a contract with a talent agency, and was about to become a star of tomorrow, she decisively and cruelly chose to part ways with him.
Three years later, Bai Qingge became the leader of VITAMIN, the idol group that turned everyone upside down on the stage. At a new album signing event held by his agency, Si Feiwei suddenly appeared and paid a high price for his one-day date. She even pretended to be a handyman and sneaked into his crew. She waited patiently regardless of time and money, distance and hatred. This made Qingge, who could not forget the pain of the year, no longer able to maintain the peace of the past, and finally slowly collapsed.
And just when Si Feiwei was getting closer and closer to Qingge, Min in the group expressed her affection for Feiwei, and her manager Liang Yeying issued an expulsion order against her... She returned with a simple purpose, but it made things more and more complicated...
What does she want from Bai Qingge who sticks to her like a piece of brown sugar? Bai Qingge's choice: reunion or crazy revenge? Three years ago, for what reason did she end their beautiful future? Three years later, for what reason did she pursue him for thousands of miles? And as Qingge's good brother, what role will Min play in the entanglement between the two? Can Si Feiwei, who sneaked into the crew secretly, get her wish despite Liang Yeying's resistance? In the green years, who betrayed whom? Who is lost in love? Who grudges the hurt? Who can't forget the tenderness of the past? What is the truth and ending?
How much sadness they have scattered in so much time, and how much strength they have accumulated in so much time?
