An office worker, Hotei, is not pleased when high-flyer Ebisu is transferred to her branch. Their personalities immediately don't match, with Ebisu strict way of doing things inevitably overworking Hotei and causing stress, and that only generates further conflict. Hotei is not entirely without fault either, as her way of taking things might have been too easygoing.
However, something starts to stir inside of Hotei and uncontrollable feelings start to surface, like a poison seeping into her body, the more she finds about Ebisu. Will these two women manage to get along, and maybe something more?
