Centered on the bond between Lin Wanxing, a restrained academic from the Computer Science Department, and Su Xia, a dynamic girl from the Journalism Department, the complete growth trajectory from campus to society is connected in series. From the conflict over spilled coffee when they first met, to the silent helping hand in the backstage of military training, to the tacit partnership in classes, competitions, and internships, the two warmed each other with their own light - Lin Wanxing used technology to escort Su Xia, and Su Xia used enthusiasm to dispel Lin Wanxing's loneliness. Facing the trough of failing in programming competitions and being rejected for internships, they supported each other; when they faced separation when they graduated, Lin Wanxing's resolute pursuit allowed the friendship to continue. In the end, working side by side in the workplace illustrates the most touching companionship in youth: not one-way attachment, but two-way achievement, so that each other is never alone on the road to growth.
