One hundred years ago, there was a young boy who was seeking a unique rose for his beloved girl. It was a freezing winter night, all roes had died. After a long time searching in the withered rose bush, the young boy was desperate. Touched by his true love, a nightingale, who heard and understood his wish, sung all night under the cold moonlight. Just before dawn, a rose stained with the blood of the nightingale, bloomed, bright and fragrant.
