With no hobbies, no friends, no lover...basically nothing worth living for, Koki is a convenience store clerk who lives his life by inertia. And tonight he was stabbed to death by a thug by accident, and in his fading consciousness, he saw a beautiful angel with pure white wings. He thought he was being welcomed home, but when he returned after recovering completely, he found the angel there in his room... Puzzled by the angel's antics, and taking pity on the fact that he has no memory and cannot fly, he decides to leave the angel there for a while. The days with the angel, however, sprouted a certain feeling in Koki's heart, who had previously been living as if he were dead.
