Yu Yan was originally a street singer and songwriter with a kind and simple personality, sweet and lovely personality. Due to the sudden death of her mother when she was a child and the bullying she suffered in the orphanage, she has a somewhat weak personality. By chance, her singing attracted a talent scout, and she accidentally entered the Starlight group. However, because of her identity as a girl, she suffered a lot of rejection from other team members and the outside world. In the difficult situation, she relied on her own hard work and unique charm to not only gain a foothold in the team, but also made the other two members of the Starlight group, Lu Jingchuan and Lu Yiyang, fall in love with her. . . . . .
