Ria Kashii worked part-time at the same restaurant as Bunmei, who always came across as a smooth-talking, easygoing friend—more like a close girlfriend than anything else. One day after a post-work drinking party, they missed the last train, and Ria invited Bunmei to stay over at her place. With no romantic awareness of him as a man and completely letting her guard down, everything changed when Bunmei suddenly declared, "I'm a man too, you know," and kissed her, shaking Ria to her core. That single moment became the turning point, setting both of their feelings into motion.
