Aoshima and Yukino work at the same company but have never exchanged more than passing glances—until fate throws them together one night at Yukino’s favorite bar. A casual encounter turns chaotic when Yukino, in the middle of a call with a friend, suddenly remembers a promise: she’s supposed to attend a wedding next week "with her boyfriend." The only problem? Her relationship ended six months ago. In a panic, she blurts out her situation, unsure of what to do.

Desperate for a quick fix, Yukino turns to the last person she expected—Aoshima—and asks if he’ll pretend to be her boyfriend for one day. To her surprise, he agrees without hesitation. Yukino is relieved, but little does she know, Aoshima has his own reasons for saying yes.

As they navigate the tricky waters of their "contract love," Aoshima begins to develop feelings for Yukino, despite having no interest in her before. Meanwhile, Yukino finds herself caught off guard by the mean yet irresistibly charming younger man she's roped into this scheme. As the wedding day approaches, sparks start to fly, and their fake relationship might just turn into something real. But with a tsundere twist, where will this unexpected romance lead?
