On a rainy night in Bincheng, architectural designer Su Wan unexpectedly reunited with Gu Yanchen, president of the Gu Group.
Five years ago, they were each other's first love on campus, but due to family barriers, malicious calculations, and unexplained misunderstandings, they broke up tragically. She moved away to a foreign country, and he closed his heart.
Five years later, the former lovers became parties A and B, entangled again in workplace conflicts. He is cold and dignified, full of guilt, and just wants to make up for his past debts and protect her properly; she is gentle and tough, with hidden obsessions, struggling between her career and past relationships.
Workplace undercurrents, family obstruction, old grievances and new confusions come one after another, and the truth about the breakup gradually emerges. It turns out that those missed moments and regrets were all caused by involuntary consequences.
He fought against the whole world for her, and she put down her guard for him. Her youthful heartbeat never dissipated, and her adult preference became stronger. This time, they untied all the knots in their hearts, redeemed each other, embraced each other in the evening breeze, and turned the missed time into staying together for the rest of their lives.
