Seventeen-year-old Shen Yuanshu is the always gentle and amiable monitor of Class 1, Grade 3, and an all-powerful academic leader in the eyes of his classmates.
No one knew that because of her fragile heart since childhood, even running around in physical education class became a luxury.
The arrival of transfer student Gu Wang is like a stone thrown into her peaceful life.
Until the old yellowed paper airplane slipped from his bag, and the unique creases instantly hit Shen Yuanshu's memory.
The memories of the hospital that had been dusty for ten years came rushing back. The little boy who always sat quietly on the bench and whom she had comforted and taught him to make origami airplanes gradually overlapped with the stern figure of the young man in front of her.
"This paper airplane?" She touched the tail of the paper airplane with her fingertips and asked softly, "Is it you?"
Gu Wang stared at her, his eyes filled with searching and waiting that spanned ten years.
When the physical examination report turned red again, when Shen Yuanshu was forced to give up physical education class and secretly cried in the empty stairwell, it was Gu Wang who found her.
"It doesn't matter if you can't run." He looked at her red eyes with deep and firm eyes, "I will teach you how to play football. Just like you taught me how to fold paper airplanes, let's take our time."
When he was a child, she gave him the courage to fly; now, it's him who carefully protects her entire world.
