Hayato Kobayashi harbors a dream. He recalls a period in high school when he shared a special bond with Ritsu Onishi. After school, he found himself in an empty library, his gaze fixed on Ritsu, who stood there with a striking presence. The day he kissed Ritsu's sun-darkened profile, feeling as though he were being drawn into it, vague and wandering days followed. By the time he realized what was happening, it was already too late; the two of them went to different universities, started working, and drifted apart... One day, Ritsu appears at Hayato's workplace—the Ritsu of his dreams...? This time, he definitely wants to go out with Ritsu.
