On the university campus in the early autumn of her eighteenth year, Xiluo dragged her suitcase and threw it into the stairwell, knocking it into Gu Chen's white shirt.
Gu Chen, a cool and taciturn student from the Department of Architecture and captain of the school basketball team, is the iceberg idol sought after by the whole school. He only has a tenderness and preference for the sensitive and tough girl Xi Luo from the Chinese Department that no one notices. No one knew that this seemingly accidental first encounter concealed a fateful foreshadowing that spanned eleven years - when she was seven years old, beside a haystack in the countryside, she gave him half a biscuit when he was lost, and he handed him an orange candy and made a promise, "I will protect you from now on."
From the cautious two-way secret love, to the ambiguous pull and heartbeat, to the blatant love, the exclusive preference in the details is heart-piercingly sweet; the patriarchal family preference, the strong suppression of the parents, and the awkward misunderstandings in youth have forced the lovers to break up, making people's eyes red.
During the days they were separated, they grew up individually, met at the top, and finally reunited. From school uniforms to wedding dresses, from early autumn to the rest of his life, he protected the girl who fell into the morning mist for the rest of his life.
