It would be better if it wasn't my destiny

Minano Onuma, who works at a travel agency, has just broken up with her lover of six years, and has turned 30 in the blink of an eye. At this time, a new colleague came to the company - Ureshino Ekinari. Ten years ago, the two of them had partners but fell into a physical relationship and were each other's "accomplices". Now that they meet again, Eunari still provokes her with that familiar whisper: "Are we destined?" The pleasure and desire that revived with the reunion made Sanosuno fall into despair again, but Eunari's true intentions have never been grasped - is she his destiny or a playmate? The secret relationship that she could not get rid of even after she became an adult made her indulge in it step by step. This drama is adapted from the original manga of the same name by Mizutani Ai.
