What is the relationship between Su Baicong and Ding Xian?

Su Bai has always maintained the necessary friendly relations with Ding Xian, who has neither moved feelings nor found Su Bai's mind. The Dusty Secret is a youth school drama directed by Zhang and starring Chen Zheyuan, Rainbow, Fan Zhixin, Wang Zexuan and Wang Yilan. Based on Er Dong Rabbit's novel of the same name, the play tells the story of Zhou Siyue, an unruly campus male god, and Ding Xian, a stubborn and lovely Cinderella. They gradually discover each other's advantages in daily life and accompany each other through the trough and confusion on the road of youth. The Secret of the Dark Grill captures the story core of the original novel in its creation, and goes forward bravely and shines brilliantly. It is hoped that by reappearing the struggle scene of chasing dreams and igniting youth on campus, it will bring moving and warm forward power to the audience and bring the audience back to that turbulent and fearless youth time.
