During university military training, Ye Yaning and Lin Yu are a pair of bickering rivals who can't help but get along.
They face off in combat drills and refuse to back down in class. Beneath their noisy, quarrelsome routine, feelings neither of them wants to admit quietly take root. Before they can lay their hearts bare, a sudden accident strikes. Amid misunderstandings and rumors, it tears apart the two people who were just beginning to grow closer. Graduation comes, and they cut off all contact, each setting off into the vast sea of humanity.
Five years later, they run into each other in the crowded world of work.
The sharp-edged young man and woman they once were have grown into capable professionals who can stand on their own. Reunited with the past, they find old wounds and unresolved misunderstandings rising to the surface once more. As they clash at work time and again, the truth behind that accident gradually emerges. Only after clearing away suspicion and distance can they see the burning sincerity that had been hidden behind their youthful antagonism.
Their old love never truly died. After years of separation and detours, they resolve every misunderstanding and get back together, making up to each other for all the tenderness that came years too late.
Not bad, not bad.
