Gawkish Kogure passively allows himself to be cursed by the boss of the paperclip factory where he works as a paperclip bender. One day, he finds a butterfly in his small flat and he allows the insect to fly to freedom. On another day, he finds a trespassing woman speaking strangely in his flat. He lets her stay, just like her father who turns up. In Kogure's imagination, the woman is a transformation of the butterfly and he allows a series of things to happen because of it.
