Lu Chen and Su Wan had been trading barbs since they were children. He was the school's aloof basketball star, while she was his “natural nemesis,” always ready to call him out. When Su Wan started showing up around Lu Chen all the time to help a friend deliver love letters, the whole school thought she was chasing after him. Lu Chen thought so too, secretly pleased even as he complained. It was only in the end that he realized this seemingly carefree girl had long held a place in his heart, and that his entire youth had been one long, carefully plotted pursuit of her.
