Let's call it the suspension bridge effect, shall we? A man and a woman who both experienced the same pain of a failed negotiation with a client while on a business trip end up staying in the same room... it's almost strange if nothing happens. Moreover, the man gently consoles the woman who has given up, and they even end up drinking together. Gradually, the distance between them shrinks, and once they kiss, it's as good as fallen. They seek each other out, exposing and indulging in such lewd behavior that is unthinkable in their usual workplace, engaging in ravenous sex.
