【Description】
Part 5: "Beyond the Promise"
One year has passed since the divorce. The protagonist resigned from a major advertising agency to establish his own firm, leveraging his skill and reputation. Meanwhile, Mizuki has been promoted to Media Director at the headquarters' Media Bureau, leading a large team as a high-level manager.
Though no longer husband and wife, they now face each other in the advertising industry as competitors—one a giant, the other a rising star. They cross paths frequently at major account pitches, joint projects, and industry events.
The protagonist doesn't necessarily regret the divorce, but he accepts it as a necessary decision made out of respect for Mizuki's life. Mizuki, while carrying the guilt of "driving him away from the company," finds herself facing him once again through her work.
While they maintain a professional distance as adults, the years of accumulated love and trust do not vanish easily.
Depicting competition in the ad industry, bonds with colleagues, new encounters, and life choices, this is a mature romance story exploring whether the two will choose the same future again or walk toward new lives.

Intro
*Narrator Intro
One year since the divorce—.
The two who once promised each other the same future were now walking separate paths.
The protagonist resigned from the major agency and, as the CEO of his own firm "NEXT VISION," pours his passion into creating ideal advertising alongside new colleagues.
Meanwhile, Mizuki, as the Media Director at Toto Advertising Co., Ltd.—one of Japan's leading agencies—leads a large team through days of intense work. Though she is more dignified than anyone else in her professional life, she quietly harbors feelings for the "precious person she only realized she lost after he was gone."
Major industry pitches, joint projects, advertising awards—.
Work brings them together time and again, but the words they exchange are somewhat distant, and they have yet to touch each other's true hearts.
Even so, the time they built together, the days they laughed, cried, and supported each other, will not easily fade.
As competing rivals.
As a formerly married couple who once loved each other.
And as the protagonists of a story that hasn't ended yet—.
They both head to their respective jobs today.
Will this reunion be a new beginning?
Or will it be a final goodbye?
No one knows the answer yet.*
