Lin Xiao and Su Yu meet in Class 3 of their first year at Minghua Middle School. With his sunny good looks, warmth, and outgoing nature, Su Yu gradually coaxes the introverted Lin Xiao out of her shell. They become deskmates, study together, take part in activities, and grow up side by side on their youthful campus. From strangers to friends, as their friendship deepens and love begins to blossom, they share moments of encouragement at sports meets, help each other in class, and enjoy the little things in their everyday lives. As they face academic pressure and the confusing stirrings of young love, how will they write a romance of their own?
