At the advertising pitch for the company's most important annual client, Blue Sea Group, Xu Wei discovers that her biggest competitor is none other than Gu Yanzhi, her first love, who vanished seven years ago. They repeatedly clash over proposals, pitches, and client meetings. They are evenly matched professionally, and a glance or gesture can stir up countless memories, yet on the surface they remain courteous and strictly businesslike. Work brings unavoidable contact, including joint client workshops, late nights, and business dinners. Old misunderstandings and unresolved feelings resurface with every encounter, only to be pushed back down.
When the male lead sees a potential new suitor near the female lead, perhaps a gentle business partner or client, jealousy surges within him, but he cannot bring himself to say so. When the female lead sees him getting close to an attractive subordinate or client, she feels a stab of pain but pretends not to care.
The conflict reaches its peak when, under immense pressure, one of them tries to rekindle their old relationship and win the other back, only for past hurts and present misunderstandings to ruin things once again. Or perhaps one of them quietly protects the other, sacrificing the project's interests at a crucial moment.
After many twists and turns, the misunderstanding that separated them is finally resolved. It may have been caused by family opposition, health problems, or the pride and miscommunication of their youth. In the end, they make peace and find success in both their careers and their love, moving forward hand in hand.
