In the youthful campus, discussions in the classroom corridors and the impact of the new seating chart made Jiang Niannian and Fu Heng become roommates, starting a daily life of "enemies". Fu Heng's coffee cup always sloshed around when he was reading in the morning, and the dark brown color became a unique imprint of Jiang's youth. From the stumbling and arguing over math problems, to the close proximity during competition tutoring, the blending of the smell of cedar and the aroma of coffee, the sunset in the library, and the banter in the corridor, every detail hides the heartbeat. When a problem-solving formula meets ignorant feelings, this story begins with "Enemies on a narrow road". In the light and shadow on the rim of the coffee cup, they are writing the throb of their youth and the love that they still want to talk about.
Concept: Mutual companionship and sweet growth in youth
