Yin Su, the girl blooming in the sea of flowers, is not as charming as a poppy. She is beautiful and pure, innocent and kind, but she is finally lost in the troubled world and can never return to the year when the flowers bloomed.
Wang Nan is a young man who cannot be forgotten in his memory. He is the domineering and restrained maturity of Leo. He has been waiting for her with all the poppies in the courtyard, but he cannot go back to the dreamland where everything has just begun.
Yang Mumin, the young and introverted eldest brother, uses his complete youth and enthusiasm just to protect the flower from blooming.
Suman has a suppressed family background, suppressed beauty, suppressed intelligence, she is proud, she has low self-esteem, she is sensitive, she is precocious, she lives in her shadow all her life.
In the youth of blooming flowers, no one is right or wrong, there is no right or wrong. They bloom in dreams and are buried by the ashes of time. Who will remember that the flowers bloomed that year.
