After finishing the novel The Fated Phoenix Maiden, she falls asleep and unexpectedly transmigrates to ancient times. When she wakes, Su Yao finds herself in the old-fashioned Su Residence, where she has become its young lady. Her body is weak and she cannot move, and a maid named Xiao Cui is by her side. Xiao Cui tells her she has been unconscious for three days and nights, but Su Yao has no idea why she has become the young lady of the Su family or why she fainted. As it turns out, Su Yao was the beloved young lady of the Su family. She disappeared three days ago and was only found unconscious at the entrance to the residence this morning. Just as Su Yao is lost in thought, the second young lady, Su Yao, and the third young lady, Su Yu, come to visit.

Confused by it all, Su Yao feels as if she is in a dream, yet everything seems impossibly real. In this unfamiliar ancient world, an extraordinary journey full of unknowns and challenges awaits her.
