In the summer of the driving school, 18-year-old Shen Ji met 19-year-old Lin Zhiyi.
When she hits the pole, he hands her water; when she talks, he listens; when she falls in love with someone else, he silently protects her. She stayed with him out of gratitude, but pushed him away out of inferiority complex.
When they reunited after five years of separation, she was shocked to realize that no one in this world had ever given her such pure and deep love like him.
