From the creator of "Huan Zhu Ge Ge," this is a brand new story. Xue Hua (Snow), Huo Hua (Fire), Lang Hua (Water) and Yan Hua (Fog) are four orphans, each with her own musical talent. They grew up together like soul sisters, once promised to never be apart no matter what.
But the girls eventually were adopted into different families, and they fall apart into separate path in life. Sixteen years later, Huo Hua, who now goes by Ye Fan, heard that Xue Hua has been living in France and became a singer named Angel.
In order to look for her long-lost soul sister, Ye Fan enrolled into a music academy in France. However, when she arrived, Angel was suspected to be dead, and the prime suspect was none other than Qi Yuan, Angel's ex-boyfriend and the principle of the music academy.
In order to find out the truth and to seek revenge for Angel, Ye Fan intentionally tries to seduce Qi Yuan's younger brother, Qi Fei, who also is a classmate at the music academy. But when things get out of hand, Ye Fan succumbs to Qi Fei's charms, and in the end, fake love turns into real emotion.
Confused between her heart and her head, Ye Fan leaves France to go back to Shanghai, focusing on supporting her now-struggling family and looking for her other two soul sisters, Lang Hua and Yan Hua. Qi Fei also arrives in Shanghai not long after to compete in a piano competition on behalf of his brother's French music school. Still deeply in love, he uses the opportunity to look for Ye Fan.
Not only has Qi Fei forgiven Ye Fan's mistakes, he also is determined to clear up all the misunderstandings surrounding Angel's death and win back Ye Fan's heart.
