Bibi, the Great Devil, came to live in the human world from the underworld. The next winter, he found a human baby in front of the mansion. Because the baby showed a smile like a flower, she was named "Flower" and raised her carefully. Bibi, a demon who will wither when receiving flowers, cherishes this "flower" with the same name as the flower, and even dares not touch her, and there are small flowers who feel lonely about it. However, after 14 years, the grown-up flowers began to care about the existence of Bibi.
