In her previous life, she fell in love with a practicing monk, and the monk pushed her into the Cliff of Forgetfulness because of the breakup of their relationship. And because of her unwillingness, she left behind her inner demons.
In this world, she was originally a bluebird in the mysterious forest, and accidentally learned that she was a human in her previous life. It takes an animal thousands of years to reincarnate as a human being, and it only takes a single thought for a human being to become an animal.
So, she turned into a human and went to the human world to find the truth.
The monk who reincarnated with her knew her past life, so he kept her by his side. Should he continue his relationship or break it? Only the monks themselves know.
However, the inner demon from her past life has been spying on her for a long time in order to get her reincarnated soul.
