Since childhood, Mai has had a strong admiration for Sumire, who is six years older than her. He becomes obsessed with her to the point that he puts up a picture of her in his room, and he studies hard to get into the same university that she graduated from, but Sumire becomes the CEO of a company at a young age and rises above the clouds. Still, I still want to get closer to Sumire, so I apply for an internship at Sumire's company. However, the true nature of Sumire that she saw there was different from what Mai had imagined. Although Mai is confused by the gap, she begins to feel more than admiration for Sumire.
