That's falling love?

Ever since Kazunari, a bar manager, took Ui under his wing, their dynamic has been defined by warmth and constant affection. Yet Kazunari adheres to a complicated philosophy regarding romance, leading him to stubbornly deny the depth of his own emotions. Despite these persistent deflections, Ui refuses to back down, determined to push their bond beyond its current boundaries and discover if their connection can evolve into something truly meaningful. In a separate tale, Rui and Saeki share a volatile chemistry, sparking like fire meeting oxygen whenever they cross paths. Even so, Rui cannot bring himself to abandon the ill-tempered, heartbroken Saeki when he is far too intoxicated to find his way home alone. The real question lingers in the air: what exactly will unfold between them once Rui finally gets him through the door? This collection also includes an additional bonus chapter that expands upon the first story.
