Chu Xijin had a crush on someone for many years. When he was young, he went to learn music because of one of his songs. And that person liked him early on, and it was because of him that he chose clothing design. Chu Xijin went to the same university as him because of that person. They met many people and things in this university, some happy and some sad. But the good times didn't last long. The senior man disappeared. Chu Xijin searched for him for five years. In five years, he became famous. However, the costumes for each of his performances were designed by well-known costume designers, and each piece was not for sale. Later he learned that Song Ruoci never broke his promise. Later, that person came back and the two got together. During the two years they were in love, Chu Xijin wrote a song for him. He planned to sing it in a global concert to people all over the world, so that everyone would know this love. It's a pity that that person disappeared again, Song Ruoci disappeared and could never be found again.
Concept: Secret love is torturous and painful, but once we are together, losing it is far more painful than having a secret love.
