While aiming to become an illustrator, Koharu works in an editing department. In her free time, she dedicates herself to a video game starring her digital prince, Nobunaga. Koharu used to be a total normie until she was betrayed by her beloved boyfriend, but since then she's been afraid of romance and retreated into gaming... One day, her sister brings home Takumi, who's in a pickle due to losing his luggage upon arriving from the US, and he happens to look just like Nobunaga...?! Though Koharu is resistant at first, he ends up staying with them while he searches for his luggage. And on top of that, now Koharu has an illustration gig to handle, too?! Koharu gives it her all, but the job falls through anyway, leaving her depressed. Seeing this, Takumi offers some encouragement, which lightens Koharu's heart. But, when his luggage is found a few days later, it seems Takumi is leaving Japan to return home...?!
