Before the castle was destroyed, Su Lingfang (played by Athena Chu), a princess of the "Fragrant City" in the paradise, was put into a boat by the castle owner and drifted down the river. She was rescued and adopted by the priest of the church. Although Su Lingfang, who has a strange fragrance, was born aphasic, she has a heavenly voice that can move the world with a word "ah". The cruelty of time took away the priest and buried her mysterious life experience. The mute girl who lived alone accidentally saved Jiang Shaojun (played by Tashi Dunzhu), a rich man born in the 1980s who was hiding from his enemies after his father fell from power. Jiang Shaojun, who was seriously injured, fell in love with this naive girl while recovering from his injuries and promised to protect her for the rest of his life. But living in seclusion for a long time made him miss the past life of luxury in the city. An unintentional phone call with Lao Ou (played by Cheung Tat-ming) exposed his whereabouts, and he was caught and imprisoned by his enemies again. In order to find Jiang Shaojun, Su Lingfang came to this real world that she had never been in contact with alone, and finally got together with her lover after several setbacks. Jiang Shaojun, who initially wanted to use Su Lingfang's natural voice to make a comeback in the entertainment industry, finally found the redemption of his soul under the baptism of true love, and protected the girl he loved in his own way.
