They are the most dazzling beings in University C - Gu Yuchen, the genius school girl from the Computer Department, and Su Wanxing, the iceberg school girl from the Foreign Languages Department. On campus, they are two parallel lines that never seem to intersect. Gu Yuchen hid his turbulent secret love deep in his heart and silently watched her cold figure; Su Wanxing sealed that cautious heartbeat in his diary and looked up at his confident light from a distance. A misunderstanding during the graduation season separated them for four years.
Four years later, fate reunited them at "Xingyao", Haicheng's top multinational technology company. He is the new technical director who returned from overseas, and he is sharp; she is the project team leader who worked hard from the bottom, and is tough and calm. The embarrassment of reunion, competition in the workplace, and past knots are intertwined. The undercurrents of the past have gradually turned into collisions and trials in the workplace, from competitors who don't trust each other, to partners who fight side by side, to lovers who can't let go. Together, they experienced the fierce competition for project bidding, the brutal baptism of industry competition, subtle differences in family backgrounds, and in-depth discussions on future planning. When the turmoil of career and the test of love hit at the same time, two hearts that had been cautiously close finally bravely crossed the gap of time and distance, from a youthful and ignorant campus crush to a marriage where they supported each other and shined together. This is a two-way journey that begins with heartbeat and ends with a white head. In the long river of time, only each other is always the most dazzling existence.
