Su Yue and Lin Yu have been neighbors since they wore crotchless pants. One is a "little bully who protects shortcomings" who often comes up with clever ideas, and the other is a "other people's kid" who keeps busy with questions. When Lin Yu's father was disabled due to a mining accident, Su Yue would stuff the candies hidden under the pillow into his schoolbag; when Su Yue was tortured by math problems and scratched her head, Lin Yu would draw little ducks all over the draft paper to make her laugh. From stealing grapes from Mr. Wang next door and being chased for three streets, to using notes to pass "information" in class to avoid the teacher's surprise questions, the two little ones carved the secret symbol "SY+LY" amidst the chirping of cicadas.
No one thought that the poor boy who always helped Su Yue tie his shoelaces would become the world's richest man at the top of Forbes list many years later. When Su Yue saw Lin Yu in a suit on the news, she was about to tease him about "having the potential to be a domineering president since childhood", but he pressed her against the floor-to-ceiling window and kissed her until she was breathless: "My lady, from the moment you put the Band-Aid into a bow, you should have known that I want to monopolize all your 'partialities'."
From urban villages to Manhattan, from pinball soda to champagne towers, the story hides the clumsy romance of childhood sweethearts - such as the orange-flavored throat lozenges always kept in Lin Yu's office, and the yellowed paper airplane deep in Su Yue's drawer, which reads: "When I become the richest man, I will pick the stars for you."
The sweetness is beyond the limit, and the laughter and tears are intertwined. Let's see how the sweethearts from school uniforms to wedding dresses turn "growing up together" into "exclusive for life".
