Liu Hui, a high school teacher, is trapped in a life of two points and one line, and love has not yet arrived. Once after school, she reunited with Li Hang, uncle of student Li Ming. It turned out that the two were junior high school classmates. Memories of the past flooded into my mind, and the ignorant feelings of my youth were rekindled. As they get along continuously, they untie the knots they have had for many years, wandering between daily necessities, rice, oil, salt and the romantic past. A love that spans time unfolds, composing a heart-stirring love song in ordinary life.
