Ueno, a cool and serious member of the accounting department, and Kanda, a bright and sociable ace of the sales department, seem like complete opposites at first glance. However, no one knows that Kanda is actually close friends with Ueno, spending a lot of time at his house. Even after Kanda reveals he's gay, Ueno is left with mixed feelings as Kanda continues to approach him unguardedly. Meanwhile, Kanda has been feeling increasingly uneasy ever since Ueno declared to him in the past, "Nothing will ever happen between us." As they spend time together as friends, their presence in each other's lives gradually grows stronger.
