In her previous life, An Xiulan had been oppressed and tortured by the members of Duke An's household. Her legitimate status wasn't enough to save her from the schemes of jealous siblings. For sixteen years, she tolerated the oppression inflicted on her but in the seventeenth year, she was pushed to death into the frozen lake.

Now she has reincarnated into the body of a youthful girl in the modern world who died in a car accident. She was given everything she was devoid of in her last life– family, love and education.
