'Kagei' is troubled by how to become friends with his junior 'Aomi Kana', who is always cold to him at work, so he invites her out for drinks. At first, Aomi just complains, but as she drinks more, she starts acting strangely! And then she even confesses that she actually likes him!!! He thought it was just because she was drunk, but then she says, "If you don't believe me that much, I'll prove that I like you, senpai," and takes him to a hotel...!?
